- A child figures ‘how many’ with this thinking - "I saw groups of tens and twos, so 10, 20, 30, 40, 42, 44, 46...46!"
- A child decomposes by saying, “I have a 10-rod, so it has 10 units of one.”
Help your student become a(n) Conceptual Subitizer with Place Value
Game-like activities ask children to name the total number in two sets, each of which has some 10s and some 1s (best in fives and tens frames). Remember for conceptual subitizing, ask them to name the total first, but then explain how they knew by naming the (preferably two) parts they saw.
