These colorful task cards are perfect for reviewing how to compare decimals. They include 24 cards, with a recording sheet and answer key. Decimals have digits up to the thousandths place.
Cards are meant to have students think deeply. They start easy for students to build confidence, and then get more difficult. Students must realize that decimals with more digits aren't necessarily bigger. For instance, 0.204 < 0.3 even though 0.204 has more digits.
Use these as a whole class activity, with students walking around individually or with a buddy. Or have students use them during a center and hang up the answer key for them to check their answers.
