Comparing Objects by Length with Child 21
A child directly compares the lengths of two objects.
Focus on the Child videos are taken from one-on-one interviews with individual children. The interviews are designed to elicit evidence of children’s mathematical thinking. They are not teaching episodes or formal assessments.
Why is this important?
Direct comparison of two lengths is a natural way to verify visual perception.
