Instructions

Play through this interactive game to learn about Understand Unit Rate As A Comparison To 1. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Ratios happen when there are two or more quantities related.

The unit rate is a comparison and does not refer to the units (cups, feet, secs etc.). The unit rate shows the relationship to 1, “for each 1” or “for every 1.”

Ratios can have the same units (ratios) or different units (rates). The term Ratio can be used for same and different units as well.

Ratios can be represented as words (5 to 3, 5 for every 3, 5 out of every 3 and 5 parts to 3 parts).

There is more than one correct way to express a ratio, all ways are interchangeable.
