How can you tell they’ve got it: Representing Numbers?

If they’ve got it, you’ll see things like: Place a two-digit number on a 0–100 number line in approximately the right position; Estimate 'about how many' objects are in a set of 30–50 without counting; Represent the same number using base-ten blocks, a number line, and a drawing; Represent a three-digit number using base-ten blocks, a number line, or a place-value chart; Estimate where a number falls on a 0–1000 number line; Match a base-ten representation to the correct numeral. Or just try it together: Can your child show a number like 346 in different ways — as base-ten blocks, on a number line, or as a drawing — and explain what each representation shows?

Mathematics Number Representation & Place Value Ages 6–8

Representing Numbers

Your child can show a number in different ways — with blocks, on a number line, or as a drawing. They can also guess about how many are in a group.

In curriculum terms

Identify, represent, and estimate numbers using different representations including the number line
