I used this whole group and small group in both my first and second grade classes. Helps move them away from finger counting into more mental math.

My students love subitizing dots as part of our number talks. They are getting more practice with finding patterns in pictures and using mental math strategies to explain their thinking aloud. I do feel like this resource could have included more for the price (I’ve found others that include subitizing ten frames, connecting cubes, etc. for similar), but I still liked this.
