1st grade math · Unit 1: Adding and subtracting within 20

Five and some more

What this lesson shows

A ten frame shows 8 as a full row of 5 and 3 more, and 13 as a full frame and 3 more. See the parts and say the total without counting each dot.

The worked example

The lesson works this one step by step: 8 dots in a ten frame. Then your kid tries one like it on paper.

The steps

  1. A full row is 5
  2. A full frame is 10
  3. 5 and some more, 10 and some more
  4. Say how you saw it

Helping at home

Show each box for a moment, then cover it. Your kid says the parts they saw, like "5 and 3" or "10 and 3", then writes the total. Ask how they saw it, not only how many.

If your kid gets stuck

Find the full row or the full frame first.
