Subitize? What's Subitize?
Subitizing is instantly seeing how many!

Subitizing will prepare your child's mind for all kinds of numeracy skills. Math is more than memorizing facts and procedures. A truly mathematical mind will develop understanding of numbers and the connections between them. Subitize Me will teach children to visualize groupings of objects, knowing their number instantly.
