Structuring number is the ability to combine and partition numbers without using counting-by-ones. Instead, the knowledge of doubles and the five and ten structure of numbers (using five and ten as anchor points) is used. Children are taught combining and partitioning to five, then ten and twenty.

Structuring from 1-10 provides an important basis for moving beyond a reliance on counting-by-ones. Structuring to 20 provides a crucial basis for the development of mental strategies for addition and subtraction involving 2-digit numbers.
