I like to use these cards to develop number sense with my kinders! I laminated and cut out the cards and pulled them out when we had extra time and used them as flash cards! Sometimes we lined up in 2 lines and raced against each other. Its a fun way to help reinforce that number sense and quick recognition. I started with 5 frames at the beginning of the year and moved on to tens frames, which you can also find on my store!
