Sensational Math How Many Cards
Large 5" x 5" activity cards build perceptual and conceptual subitizing skills with simple dot patterns on up to larger sets of dots in array and symmetrical patterns. Level I presents simple dot patterns to practice subitizing numbers up to 20. Level II provides simple and grouped patterns for numbers up to 50. Level III presents symmetrical and predictable dot patterns to conceptually subitize numbers of dots up to 100. Each setcontains 50 two-sided, self-checking cards.
