WHAT TEACHERS ARE SAYING...

⭐⭐⭐⭐⭐ "Subitizing cards are the best way I’ve found to improve number sense once the kids have lots of experience counting objects and understand one-to-one correspondence. My kindergarten students have made tremendous strides using these cards. We are not even using the term “addition “ at this point, but they know how to break a given sum into various groups (addends), form groups to make ten, etc. They are picking up many concepts just from repeated exposure to the cards and discussion, rather than my trying to “teach” the concept up front. This is a great resource! " Dianne D.

⭐⭐⭐⭐⭐ "This was such a time saver for me during our distance learning. My students loved the activities. Thank you so much!" Kelli C.

⭐⭐⭐⭐⭐ "Clever format and very helpful for kids to see the relationship between addition and subtraction! Thank you for sharing your talents!" Kathy D.
