Graphic Organizers (GOs)
A graphic organizer is a tool or process to build word knowledge by relating similarities of meaning to the definition of a word. This can relate to any subject—math, history, literature, etc.

Why are Graphic Organizers Important?
• GOs connect content in a meaningful way to help students gain a clearer understanding of the material (Fountas & Pinnell, 2001, as cited in Baxendrall, 2003).
• GOs help students maintain the information over time (Fountas & Pinnell, 2001, as cited in Baxendrall, 2003).

Graphic Organizers:
• Assist students in organizing and retaining information when used consistently.
• Assist teachers by integrating into instruction through creative
approaches.

Graphic Organizers:
• Heighten student interest
• Should be coherent and consistently used
• Can be used with teacher- and student- directed approaches

Coherent Graphic Organizers
1. Provide clearly labeled branch and sub branches.
2. Have numbers, arrows, or lines to show the connections or sequence of events.
3. Relate similarities.
4. Define accurately.

How to Use Graphic Organizers in the Classroom
• Teacher-Directed Approach
• Student-Directed Approach
![Page 8: Graphic Organizers](https://reader033.vdocuments.mx/reader033/viewer/2022050820/56815968550346895dc6a64d/html5/thumbnails/8.jpg)
8
Teacher-Directed Approach
1. Provide a partially complete GO for students
2. Have students read instructions or information
3. Fill out the GO with students4. Review the completed GO5. Assess students using an incomplete
copy of the GO
![Page 9: Graphic Organizers](https://reader033.vdocuments.mx/reader033/viewer/2022050820/56815968550346895dc6a64d/html5/thumbnails/9.jpg)
9
Student-Directed Approach• Teacher uses a GO cover sheet with
prompts– Example: Teacher provides a cover sheet
that includes page numbers and paragraph numbers to locate information needed to fill out GO
• Teacher acts as a facilitator• Students check their answers with a
teacher copy supplied on the overhead

Strategies to Teach Graphic Organizers
• Framing the lesson• Previewing• Modeling with a think aloud• Guided practice• Independent practice• Check for understanding• Peer mediated instruction• Simplifying the content or structure of the GO

Graphic Organizer Summary
• GOs are a valuable tool for assisting students with LD in basic mathematical procedures and problem solving.
• Teachers should:– Consistently, coherently, and creatively
use GOs.– Employ teacher-directed and student-
directed approaches.– Address individual needs via curricular
adaptations.

How These Strategies Help Students Access Algebra
• Problem Representation
• Problem Solving (Reason)
• Self Monitoring
• Self Confidence

Recommendations:
• Provide a physical and pictorial model, such as diagrams or hands-on materials, to aid the process for solving equations/problems.
• Use think-aloud techniques when modeling steps to solve equations/problems. Demonstrate the steps to the strategy while verbalizing the related thinking.
• Provide guided practice before independent practice so that students can first understand what to do for each step and then understand why.
![Page 37: Graphic Organizers](https://reader033.vdocuments.mx/reader033/viewer/2022050820/56815968550346895dc6a64d/html5/thumbnails/37.jpg)
41
Additional Recommendations:
• Continue to instruct secondary math students with mild disabilities in basic arithmetic. Poor arithmetic background will make some algebraic questions cumbersome and difficult.
• Allot time to teach specific strategies. Students will need time to learn and practice the strategy on a
regular basis.

Closing ActivityPrinciples of an effective lesson:Before the Lesson:• Review • Explain objectives, purpose, rationale for learning the
strategy, and implementation of strategyDuring the Lesson:• Model the task• Prompt students in dialogue to promote the
development of problem-solving strategies and reflective thinking
• Provide guided and independent practice• Use corrective and positive feedback

Concepts for Developing a Lesson
Grades K-2• Use concrete materials to build an understanding of equality
(same as) and inequality (more than and less than)• Skip countingGrades 3- 5• Explore properties of equality in number sentences (e.g., when
equals are added to equals the sums are equal)• Use physical models to investigate and describe how a change
in one variable affects a second variableGrades 6-8• Positive and negative numbers (e.g., general concept, addition,
subtraction, multiplication, division)• Investigate the use of systems of equations, tables, and graphs
to represent mathematical relationships
