A child approximates the number of cubes in collections of increasing quantity. When teaching kids math, an understanding of quantity and how numbers relate to them is necessary.

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.
