Objective

By the end of this lesson, you will be able to apply arithmetic concepts to create patterns and designs using loom bands.

Materials and Prep

• Loom bands (assorted colors)
• Loom board
• Loom hook
• Math notebook or paper

No prior knowledge or preparation is required for this lesson.

Activities

1. Create a simple pattern: Start by choosing two different colors of loom bands. Using the loom board, create a pattern by placing one color in a diagonal line from the bottom left corner to the top right corner. Repeat this pattern until you reach the end of the board. Count the number of bands used for the pattern.
2. Explore number patterns: Experiment with different color combinations and create patterns using different arithmetic sequences. For example, instead of a diagonal line, try creating a pattern with a horizontal or vertical line. Count the number of bands used for each pattern and observe any patterns in the numbers.
3. Challenge yourself: Create a more complex pattern by incorporating multiple arithmetic sequences. Use at least three different colors and create a design that combines diagonal, horizontal, and vertical lines. Count the number of bands used and identify any relationships between the numbers.

Eighth Grade Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and their operations."
• "We can use arithmetic concepts to create patterns and designs using loom bands."
• "Patterns can be created by repeating a sequence of numbers or objects."
• "In the first activity, we created a simple pattern using a diagonal line."
• "In the second activity, we explored different color combinations and observed patterns in the number of bands used."
• "Finally, in the third activity, we challenged ourselves to create a more complex pattern by combining multiple arithmetic sequences."
• "By experimenting with different patterns, we can develop our understanding of arithmetic concepts and apply them in a creative way."
