- When shown 87 objects spread out and asked for an estimate, the child points to a section and says, "That's about 20 - so 20, 40, 60, 80, Eighty!" The use of repeated addition supports estimation after a visual separation of the objects into 4 parts.

Activities ask children to make reasonable estimation of the number of objects in a set, helping them form benchmarks (what would 10 of these look like? 100?) to guide their estimates using repeated addition and/or multiplication (picture 10 in the bottom of the jar--keep counting by tens up the jar). Scaffolding also includes using regular arrangements of objects and then includes more random arrangements to extend children's competencies.
