Lesson objective: Solve problems with scaled graphs.

This lesson provides an opportunity for students to apply their knowledge and understanding of interpreting graphs to a real-life situation. Students are asked to determine how many wristbands can be made from a given number of beads.

Key Concept students will use:

- Picture graphs and bar graphs can have scales other than one.

Skills students will use:

- Exploring equal groups as a foundation for multiplication and division (Grade 3, Unit 1)
- Multiplying one-digit numbers by multiples of 10
- Finding, extending, and explaining patterns

Students engage in Mathematical Practice 3 (Construct viable arguments and critique the reasoning of others) as they explore different ways to approach and solve the task of discovering how many wristbands of each color can be made.
