These dinosaur themed, subtraction within 20 cards will have your students ‘roaring’ to practice! They are a great interactive way for your students to practice or review subtraction facts throughout the year!

This clip card resource includes 230 color cards (repeated in line art). To improve function and durability I suggest copying or printing on card stock. After cutting, place a dot, stamp, or sticker on the back of the box with the correct answer on each card to make them self-correcting. Then laminate and cut again. The extra steps will take a little more time but should last you much longer.

If you’re looking for more practice, Cat and Dog themes are also available.
