Kindergarten math · Unit 5: Adding and subtracting within 10

How many more does he need?

What this lesson shows

Eddie has 5 tokens and needs 8. Count on 6, 7, 8: he needs 3 more.

The worked example

The lesson works this one step by step: 5 + 3. Then your kid tries one like it on paper.

The steps

  1. What he has
  2. What he needs
  3. Count on to it
  4. Count the numbers you said

Helping at home

Read each story aloud, twice. Your kid starts at the number Eddie has and counts on, one finger for each empty spot, until reaching the number he needs.

If your kid gets stuck

Start at what he has. Count on to what he needs.
