Fractions: Subtracting fractions using grids

 
Using Grids to Subtract Fractions
 
    
  Every year one of our greatest struggles is teaching students to subtract fractions.  There are a variety of reasons for this.  Weak basic skills, following multiple steps and in general a bad attitude about all things dealing with fractions.  We believe that one of the biggest struggles for students is the inability to visualize how fractions interact with each other.
 
     The solution for us was to teach fractions using a grid system.  We originally started using this with our math intervention students (see http://thelandofmath.blogspot.com/2013/06/our-middle-school-math-intervention.html).  We later expanded its use in our regular classes with positive results.

     The benefits of the grid system:

  • Very inexpensive
    • Just paper, a couple of markers or highlighters, and some blocks or chips
  • It is hands on
  • It is visual
  • You can work individually, with partners or in small groups
  • Set up time is short and requires minimal effort
  • Easy to model on white board or smart board
  • This lesson compliments our lessons on adding fractions and equivalent fractions (see http://thelandofmath.blogspot.com/2013/10/teaching-equivalent-fractions-using.html).
     We usually focus on fractions with denominators ranging from two (2) to eight (8).  We use this range of numbers because of ease of use, but you can go as crazy as you want.

Step one

     Give the students a subtraction problem such as 1/3 - 1/4.  Have the students draw four (4) columns with one of the markers. and three rows with another color. The four columns and 3 rows are the two denominators we are using. We like to use different color markers to help students see the fourths and the thirds on the grid.

Step two

     Have the students fill in 1/3 of the grid (4 of the 12 spaces) with one color of chips/blocks (red chips below).  Next, have the students use a different color chip (green below) to fill in 1/4 of the grid.

Creating a Successful Math Newsletter for your class

 

 
     One of the things we try to do each year is to create a math newsletter to share with parents, students and administration.  The main reason is to help develop better communication with parents.  The development of our newsletter is an ever evolving process, but we feel like we have hit on some key things that make our newsletter very effective.
 
     At the start of the year we focus on gathering the email addresses of different parents, students and any one else that might want the newsletter.  We have been able to get around 90% of our student's families to sign up.  When we send out the newsletter we just email a PDF to the different people on our email list.  We mail copies to families that did not sign up for email.  We also make extra copies and leave in the classroom for students that might not see the email version. In the past we sent out newsletters each month.  This year we are attempting to send out one a quarter.
 
     Below is a sample of a newsletter from last school year. The rest of this article will focus on the content, features and structure of the newsletter.

 
 
Page 1 of the math newsletter
 
 
#1 Headline: The first thing we do on our newsletter is state what it is and for what time period.  In this case we call the newsletter the "7th grade math newsletter" (yes we know, verrrrry creative).  If we had newsletters for each individual teacher we might have use something like Mr. Mitchell's Math Class (also very boring) or perhaps something slightly more interesting such as Math Mania.

#2 Contact Information: This part of our newsletter includes information such as Names, email address, school phone, planning period times, website, etc.

#3 Quote: We like to have a quote about dealing with one of two topics: 1) Importance of math and/or 2) Motivational.

#4 Greeting: We address this to the parents despite the fact that many of the readers of the newsletter are our students.

#5 Dates to Know: Just like it sounds. We focus on big events such as early releases, no school, end of grading period, parent - teacher conferences, etc.


    
#6 Classroom Activity:  In this section of the newsletter we highlight an activity that takes place in the classroom. For example, this newsletter mentions our "Fab 5" which is a basic skills review at the start of each class.  In this section we might mention a math program we are using, special projects, or discuss our invention program.

#7 Upcoming Topics:  In this section we list what we are currently working on in class and what parents can expect in the next few weeks.

#8 Math Careers: One of our goals is to let parents and students know about the many career options available in mathematics.  It seems obvious to us, but many students have no idea about the math needed in different careers.  A couple of weeks ago a student told me how he wanted to be an architect but was stunned to find out math was required math.

Lakewood 7th grade math teaching goals


Lakewood 7th Grade
Teaching Goals
2013-14

The following is a short list of educational goals that we want to achieve this school year.

INCREASE TEACHER MATH KNOWLEDGE


            We have spent a boatload of time this summer tearing apart the math common core standards.  Not just our grade (7th), but all grade levels from k to 8.  As we enter the school year we feel as prepared as any school year.  We want continue adding to math knowledge as the year progresses.  We are currently taking the Stanford math class with Jo Boaler which has been very enjoyable.

INCREASE STUDENTS INTERST IN MATH

            A key goal every year for our 7th grade team in to increase the student’s enthusiasm for math.  We pride ourselves on being unique and creative.  Our DeMATHa (Developmental MATH Academy) Program allows us the freedom to experiment.  Whether it’s our sidewalk probability game or our legendary Khan Academy “WRATH OF KHAN” contest (khantest?) we want to push ourselves to be innovative.

CREATE MORE OPPORTUNITIES FOR HANDS ON ACTIVITIES

            Even though we have two or three epic projects each year, we feel like this is an area that we could make tremendous strides.  We want to focus on having a minimum of one hands on project each week.

INCREASE PARENT/STUDENT/TEACHER COMMNUICATION

            We have used our monthly math newsletter for the last three years.  We will continue the newsletter, but we will supplement with a Twitter account, Pinterest page and a Tumblr page.  A major area of weakness for us has been calling (or emailing or writing) parents when students do something positive in class.  This too will become a weekly goal.

INCREASE STUDENT KNOWLEGDE AND PERFORMANCE

            Bottom line, when the year is done we will be judged by the student’s progress.  For over 7 years we have achieved the highest level of value added in Ohio.  What is nice about each school year is the opportunity to make an impact on a new group of students.

Don't fall for the seduction of the 1 cent pencil




The summer is wrapping up and the school year is about ready to kick off in full force.  This is the time of the year that is filled with optimism and excitement. Everything starts over.  Students get to meet new teachers, teachers get a new batch of students and parents get a chance to regain their sanity.

Despite all these warm and cuddly feelings that surround the start of school I am dreading another yearly tradition: parents buying their kids crappy pencils.

Don’t get me wrong, I to have been seduced by the allure of the 1 cent pack of pencils at Staples (or Wal-Mart, Kmart, etc.). As a parent you feel good about making such a wise purchase. After all a pencil is just a pencil.

“No so fast my friend,” to quote Lee Corso, the legendary football analyst from College Game Day (and Director of Business Development for Dixon Ticonderoga pencil company).  Pencils are NOT all the same and it DOES make a difference.

Educations Directly Responsible Individuals



It is a beautiful day outside.  The temperature is in the mid 80’s; it’s sunny, low humidity, peaceful with a light breeze.  Most people would probably agree that this sounds like a very pleasant day.

Most of us could agree on the key factors that make up a beautiful day, but there would be a lot of debate on how to assign a value to each.

For what it is worth I would assign the following values: temperature = 40%, humidity = 20%, sunny = 20%, Breeze = 10% and Peaceful = 10%.

It is impossible to assign a value to every element that makes up a beautiful day.  Each part of the day is important and relies on the other elements to make up the day.  If just one of these elements is off (no sunshine, high humidity, etc.) the quality of the day suffers.

As silly as it is to say that a light breeze makes up 10% of a great day it’s equally silly to give different teachers a percent of a student’s success or failure.

This year the state of Ohio began the process of linking student achievement with teachers.  I am one of the biggest fans of holding people accountable.  In theory this sounds like a no-brainer, but there are a variety of problems with Ohio’s linkage system.

If students only had one math teacher this would be very easy to do.  The problems begin when students receive assistance from other teachers.  At my school nearly 50% of all students receive some sort of intervention from other teachers.

In addition to the normal regular education class, our school has a daily intervention class with two teachers, an academic assist class that meets twice a week (also two teachers) and some tutoring provided by a non-degree teaching assistance.

When it’s time to assign a percent of each student it can be confusing and very inconsistent.  Not only do school districts differ, but even teachers at the same district might use different criteria to divide up value for students.

There are many variables that can make it complicated to assign value for student growth.  The minimum a teacher can receive is 20% credit, the values must be in multiples of 10 and non-certified staff can't receive any credit for student growth.

For example, Roger is in my 2nd period math class with an intervention teacher has a daily math development class (that is team taught) and receives one period of tutoring per week.

Now we must determine who is responsible for what percent of Roger’s academic performance.  Because he was tutored by a non-certified staff member the tutor receives 0%.  The developmental class is a bit trickier because I taught it with the other math teacher.  Because the minimum a teacher can receive is 20% we each take 20% credit for Roger.  This leaves 60% to split with myself and the intervention teacher.  The intervention teacher received 20% and I received an additional 40%.

The final totals:

          60% Regular Education teacher

          20% Intervention teacher

          20% Other math teacher

          0%   Tutor

As a side note: A school 30 minutes down the road gives the regular education teacher the full 100%.  All other teachers (intervention, gifted, etc.) receive no credit.

I love holding myself and others accountable for productivity.  I admire Apple’s (the computer company not the bribe to a teacher) Directly Responsible Individual (DRI) practice in which an action list is created for every task and a person (the DRI) is listed next to it.  I certainly believe Apple’s DRI Model can be very effective when applied to education.  Linking student performance to teachers is Ohio’s attempt to incorporate a version of the DRI Model.

Despite my admiration of the Directly Responsible Individual Model I have some major concerns about how Ohio is implementing Linkage.

Creating a culture of Covering Your Ass (CYA) vs. Building Effective Teams (BETS)

As in most aspects of society teachers will quickly learn ways to game the system.  Linkage will encourage teachers to take care of themselves instead of making sacrifices to help the team.

Teachers will begin to study the types of students that will give them the greatest chance to achieve growth.  In most cases it will be the highest performing students.  There will then begin a recruiting process among teachers.  If your school ability groups there will be wide spread competition for the better groups.  No teacher is going to want to get the students that struggle to show growth.

Determining the percentage each teacher receives will create uncomfortable situations for the teachers.  At our school it is up to individual teachers to determine who gets what percent.  An intervention teacher in 6th grade might receive 30% while the 8th grade teacher might receive 50%.  An intervention teacher receiving only 20% might feel bitterness toward the person they are working with.

Teachers are going to be less likely to work with students that struggle to show growth during intervention classes or tutoring.  At our school a few students in our developmental class were from the resource class.  Even though we never had these students in regular class our mindset was to help any kids that needed extra assistance.  We knew that there was a good chance that these student’s scores would drag down our individual performance, but we wanted to help the 7th grade as a whole.  There are many teachers that will not want to take on additional students with a high probability of failing the state test.

Some schools in Ohio have a financial reward for teachers based on student growth.  In theory this sounds like a great thing, but it’s another way to create staff friction.  The teachers that work with the weaker students will more than likely receive smaller bonuses. In addition, teachers in subjects like social studies, science and computers will have no opportunity to receive these bonuses. 

Another source of possible friction is teacher evaluations.  A large part of a math (and language arts) teacher’s evaluation comes from the student growth on state test. Other subjects just make up their own assessments.  These other teachers have a much greater chance of showing growth.

Teachers are also going to become even more reluctant to accept student teachers.  The only way for future teachers to improve is to actually teach a class and learn from their mistakes.  The more experience the better the future teachers will become. But with teacher evaluations, student growth and possible bonuses on the line fewer teachers are going to be willing to give up their classroom to student teachers.

As a side note: Mount Vernon Nazarene University in Ohio has changed their student teacher program.  The students will team teach with the regular classroom teacher, instead of going solo.

The Missing Directly Responsible Individuals

Even though I have my concerns with Ohio’s Linkage system I think in general it’s a step in the right direction.  I believe the more you blend Apple’s Directly Responsible Individual (DRI) Model into education it will lead to greater things. If it was more consistent and put a greater emphasis on teaching teams I think it could have more success.

The two key missing components in the whole accountability process are the parents and students.  You can develop the greatest lesson plans, care about the students, create a warm inviting environment, and be an expert in mathematics.  Ultimately, if the parent and student don’t care there is a limit to what the teacher can do.

The student is his own personal product manager.  The student has thirteen years of education to develop his personal product.  Along the way there are many people that will have key jobs in the students (the product) development.  But in the end it’s the student that is the Directly Responsible Individual.

Our Middle School Math Intervention Program



The DeMATHa Project: A Math Intervention Program

            This past school year we were assigned the task of developing an intervention math program for the seventh grade.  We dubbed this program the DeMATHa (Developmental Math Academy) Project.  None of the students in the DeMATHa Project had previously passed the Ohio Academic Assessment (OAA).

The creation of this project was not only successful academically, but it was a tremendous learning experience for us. Despite many obstacles, nearly 70% of all students in DeMATHa were able to successfully pass the seventh grade OAA. 

No classroom.  No materials. No students.

            That was our situation the first day of the 2011-2012 school year as we prepared to teach an intervention math class.  The previous spring our district spent a great deal of time, money and energy on a special reading intervention program. There were all day in-services, tons of available materials, and detailed lists of students and their reading levels.   All of the teachers in the middle school were involved …except for the math teachers.

The math department was just an afterthought. We were given the task of creating from nothing and teaching a developmental math class.  Initially we thought we were going to have two small classes of about six or seven students. It turned out there was no class roster, only one room available and no resources devoted to this program.

Initially there was discussion of the usual focus on the basics, which is nothing more than code for a lot of worksheets and repetition. As the school year approached, we began to question this approach.  Many of the students that would be in this class already had a strong dislike for math.  In addition, these students were going to be pulled out of classes they enjoyed (gym, art, computer, etc.) to take another math class.  The prospect of cramming more worksheets down their throats would not be appealing to us or them.

Finding ourselves with no students, no resources, no curriculum and limited space, we developed a math manifesto for the DeMATHa Project.  These core principals are the foundation of what we felt were needed to have success with these students.

The DeMATHa Project Core Beliefs

FUN & RELAXED

The most important objective of DeMATHa was to create a fun and relaxed environment. This is not to be confused with just goofing around.  We knew our only chance to help these students was to create a situation that was enjoyable.  Because we had total freedom, we were not limited by the constraints of a typical classroom and we were able to customize the class to best reach the students. 

Normally teachers are concerned about covering all the required material, but we had no required material.  When we covered a topic in class we took our time to insure that the students fully understood. Many times a one-week lesson would morph into a two week lesson.  Because of no time constraints, we could take as long as needed and present material in a variety of ways

We also included students’ input in the creation of the class.  During the first week we had the students peruse their math textbook and list topics in which they were interested. We then had the students vote on which topics to cover first.  In addition, we incorporated student interests into lessons.  For example, some students had an interest in hunting.  Throughout the year we found a variety of ways to incorporate hunting into some lessons such as a circle graph of favorite animals to hunt.

Another key to winning the students over was the use of humor.  There is a fine line between being entertaining and playing around.  We were able to enjoy humorous moments that naturally occur in class.  In addition, as teachers were able to play off of each other’s sense of humor.  We believe the students could sense that we were enjoying ourselves which resulted in a less threatening class.

Team teaching had an added benefit of allowing us to deal with issues as they occurred without slowing the momentum of the class.  Sometimes a student would be dealing with issues from home and these issues would spill out into the class.  With team teaching we were able to calmly take the student somewhere quiet and get to the core of the problem.  Many times the student just wanted to vent to someone.  Sometimes there were issues that we were able to directly address.  The bottom line is that we could keep the class calm and minimize conflict while at the same time building trust by showing the students that we were concerned with their welfare.

LIMIT WORKSHEETS

The second principal of DeMATHa was to try to avoid using worksheets and focus on hands on activities. The class would be made up of students with a strong dislike for worksheets.  As teachers we did not want to fall into the trap of over reliance on worksheets.  

We still used worksheets, but less than ten percent of what we would use in a normal class and with far fewer problems.  When we used a worksheet it was usually accompanied by manipulates such as algebra tiles.  Also, we did not assign homework which helped to reduce the amount of worksheets.

BIG CONCEPTS vs. BASIC FUNDAMENTALS

Third, we wanted to focus on bigger concepts.  We did not want to get bogged down on basic fundamentals.  Instead of spending a lot of time on topics like long division we wanted to focus on bigger topics like probability and understanding how to write equations.

The Ohio Academic Assessment for math does not test basic computation skills and allows the use of a calculator.  The OAA focuses on the student’s ability to use basic computation skills to solve more complex problems.  For example, instead of having the students multiply  the question might ask: “A cake is cut into three equal slices.  Tim eats ¼ of a slice.  What fraction of the cake did Tim eat?”  The student could use a variety of strategies to solve this problem such as multiplication, division or sketching out a visual model.

This is not to say we ignore student weaknesses in basic math skills.  We have a period each day called academic assist in which we tutor students on fundamental weaknesses.  We also use a basic skills review at the beginning of each class as a way to practice and chart progress of student’s basic skills.

VARIETY:  THE SPICE OF MATH

The fourth core belief of DeMATHa was variety.  We did not want to get in a rut doing the same thing each day.  Every day we tried to keep the student wondering what was next.  When we were working on ratios and similar objects we took the class on a “field trip” to the teacher’s workroom and used copiers to shrink and enlarge different items.  We tried a variety of art projects, played math games (our favorites: XP Math & Hooda Math) in computer lab, created Khan Academy accounts and tracked progress, let students use the Smart Board, used in class games/competitions, varied students ability to work individually, and allowed partners or group work in addition to many other items.

In addition, the topics also varied.  We made a concentrated effort not to cover topics currently or previously taught in the regular math class.  This created an atmosphere of discovery and not just reviewing material.

In sum, we always wanted the students to be curious about what was next.  If we ever felt things were getting stale, we immediately tried an activity that was 180 degrees from what we had been working on to keep their focus.

DeMATHa – A reflection

            In general we were very pleased with the progress of the DeMATHa students.  One of the best rewards came from watching the students in their regular math class.  Because these students had previously been introduced to the lessons, they had a swagger when these concepts were presented to the other students.  You could see the excitement in their eyes when they realized that they were ahead of other students in their math knowledge.  This newfound confidence in math resulted in greater participation in class and kept DeMATHa students focused.  In many cases the DeMATHa students would assist other students.  Also, the increase in confidence gave these students the fortitude to press on when they would encounter difficulties.

            The benefits of tandem teaching were something we had not expected. Our focus had always been divide and conquer.  It was just assumed that a small group with one teacher was the most effective way to operate. For us, combining these two small groups and working together was far more productive.

            Our core beliefs of a fun & relaxed environment, limited worksheets, focus on big concepts, and variety were reinforced with the DeMATHa Project.  The success of the project has led us to revamping how we structure our Academic Assist Period.  There are even certain elements, such as greater variety, that we can incorporate into our regular math class.  We are also exploring the development of a DeMATHa class for the gifted math students.

            The value of the DeMATHa project is supported by the numbers.  Prior to participation in the DeMATHa project, students had a 0% passage rate on previous math Ohio Academic Assessments.  After DeMATHa, nearly 70% of participants were proficient on the OAA.  To take students from zero to nearly 70 percent passage with a program that cost no money to our district and was created from scratch is a success, no matter how you add it.
