Counting Objects One by One

Aligned to K.CC.B.4 — Common Core State Standards for Mathematics.

What this lesson teaches

When we count, each object gets exactly one number word, in order. The last number you say tells how many there are in all.

Worked example

Count 5 blocks: point to each and say 'one, two, three, four, five.' There are 5 blocks — the last number, 5, is the total.

Practice questions

  1. Count a row of 6 crayons out loud, pointing to each.
  2. If the last number you say is 8, how many things are there?
  3. Count 4 toys, then add one more — how many now?
