Pipe cleaners (multiple colors)
Duct tape
Scissors
Ruler (optional, for measuring)
Preparation: Cut pipe cleaners into appropriate lengths to represent different fractions. Use duct tape to secure the pipe cleaners on a flat surface, such as a piece of cardboard or a desk, to create a number line.
Creation:
Design Number Lines: Arrange the pipe cleaners in a line, spaced to represent different fractions (e.g., 1/2, 1/3, 1/4). Use duct tape on the back of the pipe cleaners to secure them in place and to create the visual number line.
Labeling: Label the number line with fractions or whole numbers as appropriate. Ensure that each fraction is represented accurately.
Activity:
Visual Representation: Have students use the pipe cleaner number lines to visualize fractions and understand their relative sizes. They can use the number lines to compare fractions, add fractions, or solve fraction problems.
Hands-On Practice: Allow students to create their own pipe cleaner number lines, representing different fractions or a range of fractions, and use them for practice.
Discussion: Review the number lines with the class. Discuss how the visual representation helps in understanding fractions and their relationships.
Extension: Optionally, use the pipe cleaner number lines for interactive activities, such as fraction matching games or fraction placement exercises.
