Equivalent Ratios Lesson: Tape Diagrams, Grades 6-7

Why is 2:3 the same ratio as 6:9? This lesson answers it with a tape diagram. Every box in the diagram is the same size, so when both strips get the same number of boxes, both quantities grow together. Students see equivalent ratios instead of memorizing a rule.
