About the Lesson
This TI-Nspire™ lesson helps students to generate equivalent ratios and tables of values for ratios. Students should understand from the first activity in the series, What is a Ratio?, that equivalent ratios arise by multiplying or dividing each measurement in a ratio pair by the same positive number.
Prior to working on this lesson, students should understand:
- the concepts of multiplication and division;
- the concepts of ratios and equivalent ratios;
- how to complete multiplication tables.
