How Many? activity cards build conceptual subitizing skills with larger sets of dots in array and symmetrical patterns. By putting these dots into a grid format allows students to see the patterns and conceptually subitize larger numbers with great precision and speed. Level II provides simple grouped patterns for numbers up to 50. These card decks are great for small group practice or independent exercise as self-checking number words and numerals provide the answer on the reverse side of the card. This How Many? set of large 5” x 5” cards contain 50 two-sided activity cards.
