Try this Ordering Rational Numbers Card Sort with your 4th, 5th, or 6th-grade math students.  Have students sort these cards into decimals, fractions, and percents.  Use 20, 40, or all 60 cards depending on the age and abilities of your students.  Once all cards are sorted, then have students place the cards in order from least to greatest to show they understand ordering rational numbers.


If you use all 60 cards, you can also play a matching game.  Students try to locate one card of each form, all of which have the same value.  It’s an incredibly versatile way to get students to use rational numbers over and over.  They work hands-on, collaborate with others, reason, and more.
