# Math Graphic Organizer Guide

Using Graphics Organizers
√  to Support Math Progress
√  to Clarify Math for the Targeted Instructional Area: Writing to Learn.

 First Semester Schedule Session 1: October 22, 2:00-2:40 pm Workshop to Clarify and Expand the Use of Graphic Organizers and Writing to support Math progress Session 2: November 12, 1:20-2:00 Follow-Up Session: Assessing Progress—Teachers discuss the work in progress. Please bring examples of student work to share at this session.

Why graphic organizers?

Why writing?

What works?

Graphic Organizers increase learning.
As a tool to support students’ thinking and learning processes, the 29
research studies have shown that graphic organizers help students:
• brainstorm ideas.
• develop, organize, and communicate ideas.
• see connections, patterns, and relationships.
• assess and share prior knowledge.
• develop vocabulary.
• highlight important ideas.
• classify or categorize concepts, ideas, and information.
• improve social interaction between students, and facilitate group work and
collaboration.
• guide review and study.

Graphic organizers have been found to improve students’ reading
comprehension at all levels, first grade through high school. …NRP (National
Reading Panel) cited graphic and semantic organizers (including story maps)
as one of seven categories of instruction that is the most effective in

 Critical Thinking Writing develops Comprehension Content Learning

There is clear evidence that activities involving writing (any of the many sorts of
writing) lead to better learning than activities involving reading and studying only. To
improve the teaching of writing is also to improve the quality of thinking required of
students....

My Plan

To use graphic organizers as models/guides…

For students to create their own graphic organizers…

For students to write to clarify what they learn…

A message about the first day of teaching.

Source: A website dedicated to teachers helping teachers.

The following plea for help has come from a newly appointed teacher who wishes to
remain anonymous.

On the first day of my teaching career, I defined a rational number to my
class as a number that can be expressed as a ratio of integers. A
student asked me: What exactly are ratios? How do ratios differ from fractions?
I gave some answers that I was not satisfied with. So, I consulted some other
teachers and texts. The result was confusion.

I find that opinions and texts vary about the definitions of these terms. Please
tell me how ratios, rational numbers and fractions should be defined to make
their distinguishing properties meaningful to the high school students.
To convince you why it is confusing, I am giving below a sample of definitions of
ratios and fractions from different texts.

'A comparison of two quantities by division is a ratio.'
'A fraction is a comparison of two numbers. Another word for the
comparison of two numbers is ratio.'
'A ratio is the comparison of two quantities that have the same units.'
'A ratio of two quantities is their quotient. For example, the ratio
of 3 oranges to 5 oranges is 3/5.'
'A ratio is a comparison of two quantities, usually expressed as a
fraction. In fact, a fraction is frequently called a 'rational number,' because
one meaning of the word rational is 'having to do with ratios'.'
'An indicated quotient of two numbers is often called a ratio.'
'For any two positive numbers, a and b, the ratio of a to b is a/b.
This is sometimes written as a : b.'
'Any fraction may be considered as a ratio of its numerator to its
denominator.'"

The website included some recommendations. One teacher suggested a word chart.
How could such a graphic organizer help this teacher’s students get and stay clear?

Clemente Teachers’ Math Strategies Using Graphic Organizers

• Many organizers can be used with geometry or math. It’s all about ideas/creativity.

• In math we use charts, tables, graphs, Venn diagrams and many forms of time lines
to organize material or solve problems.

• Chart and Venn diagram can be used to compare different types of numbers in
algebra.

• I use a Venn diagram to categorize real numbers. Charts work well in geometry. (A
word column, definition column, simple definition column, and picture or example
column.)

• I use charts to introduce new words, and outlines to show the steps of a problem.

• Students will be given a math article, they will be asked to find words that are
exclusively math words and to write those words in the left circle (not in the intersection
part). Similarly they will write exclusively non-math words in the right circle and the
words that can be used commonly in math and non math areas in the intersection part.

• I use the circle to teach angles in my geometry class. They learn:
o How to use a protractor
o How to read a protractor
o Acute, obtuse and right angles
o x and y axis
