This I Have Who Has product contains 30 cards. The cards contain "must know" fraction, decimal, percent conversions.
I require students to memorize the following denominators that are included on the cards: 2, 3, 4, 5, 8, 9, 10, 100
There are a couple of challenging cards that may require students to find the equivalent fraction first. For example, find 2/50 as a decimal.
This is a fun and quick review for students! It works best once students have learned/memorized their most common conversions. I like to have them switch cards and do more than one round to see if they can beat their previous time!
