Representing Numbers
Mathematics · Number Representation & Place Value · representational
Identify, represent, and estimate numbers using different representations including the number line
What mastery looks 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
Check your understanding
Can Representing Numbers 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?
