Grade 4, Chapter 9 Investigation Organizer:
Weaving Fractions
Summary: You will use fractions to help you plan and "weave" a pattern. Use strips of paper of all different colors. You can also use fractions to describe your completed design.
1. Plan It
A. Choose your colors. As a group, choose the colors you would like to use. Decide what fraction of each color you want to appear in your work.
B. Draw. Draw your design on graph paper.

C. Weave. Weave color strips through the slits to match the pattern you designed.
Our weaving completed
3. Wrap It Up
A. Work together to write a report about your weavings. Use fractions to describe how much of each color your used.
B. How would you plan another weaving? How could you add and subtract fractions to change your design?
Our report completed
4. Discuss Your Results

- Did you use fractions to plan your design?
- Did your weaving match your drawing?
- Did your group work well together?
- How did other groups use fractions?
- Use fractions to describe which group used the most and least of each color.
