Kindergarten math · Unit 3: Sorting and counting

Sort, then count

What this lesson shows

10 shapes sorted into circles, triangles, and rectangles. Count each group: 4, 3, and 3.

The worked example

The lesson works this one step by step: 4 circles, 3 triangles, 3 rectangles. Then your kid tries one like it on paper.

The steps

  1. Pick one kind
  2. Find every one of it
  3. Count it as you go
  4. Then the next kind

Helping at home

Read each box aloud. Your kid finds one kind at a time, crosses each one off as they count it, and writes how many of each. Sort laundry or snacks the same way.

If your kid gets stuck

One kind at a time. Cross each one off as you count it.
