Perceptual Subitizer to 5

Instantly and effortlessly recognizes collections up to 5 (without counting) and verbally names the number of items. What separates this level from the previous level (perceptual subitizer to 4) is that a child recognizes and uses spatial and numeric structures from past experiences to subitize.

Help your student become a(n) Perceptual Subitizer to 5

Activities throughout the day naming the number in sets of 1 to 5 and game-like opportunities to name the number in sets only seen for 2 seconds or less help develop this fundamental numeracy concept. Simple, high-contrast items (e.g., black dots on white paper plates) focus children's attention on the number in the set.
