Đồ chơi giáo dục tập đếm số (Counting Numbers)

Designed to teach my son numbers and counting, and he learned it really fast.  Addition is also made easy by counting the dots to find the sum.  For 2+ digit addition you can sum them in columns which teaches place values.

Best to print at least 2 sets.

Numbers, Plus, and Equal sign are all larger than choke hazard when printed full scale.
