Number sense is such a key concept for young learners. I have found that subitizing (recognizing numbers quickly) is one of the biggest skills my students need practice with. I do this by using ten frame flash cards. They can be used in many different ways, but ultimately the goal is for the students to be able to recognize the ten frame set without counting.
I have included themed ten frame flash cards with multiple representations for each number. The themes included are:
Snowflakes, Hearts, Shamrocks, Eggs, Butterflies, Suns, Apples , Acorns, Pumpkins, Turkeys, Reindeer, Candy Canes
I have also included a simple set with just black dots.
