Counting Within 1,000

Mathematics · Counting & Cardinality · procedural

Count within 1000, including skip-counting by 5s, 10s, and 100s

What mastery looks like

  • Count forwards and backwards within 1000 from any starting number
  • Skip-count by 5s from any multiple of 5 to 1000
  • Skip-count by 100s from any number (e.g. 150, 250, 350 …)

Check your understanding

Can Counting Within 1,000 count confidently up to 1000 — and if you ask them to count by hundreds from 200, or by tens from 650, can they do it without losing their place?
