Being able to subitize and instantly recognize amounts to 20 in a variety of ways is an important skill for students in the lower elementary classroom. Ten-Frames help students make and recognize groups of ten.
This activity is fun and easy-to-use. Just print out the activity as 2-sided, then cut out the cards. Some people might use cardstock or laminate them to have them last longer.
There are 20 cards, and the questions and answers complete a circuit, so it doesn’t matter where you start (as long as all 20 cards are played).
