Series: Focus on the Child
Cardinality with Child 7
A child counts on to find the total number of cubes as the set increases.
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.
