Kindergarten math · Unit 5: Adding and subtracting within 10

Facts to 5, fast

What this lesson shows

Five fingers show every way to add and take away within 5, until 3 + 2 and 5 − 1 come without counting.

The worked example

The lesson works this one step by step: 3 + 2. Then your kid tries one like it on paper.

The steps

  1. One hand has 5 fingers
  2. Show some, then some more
  3. Put fingers down to take away
  4. Say the fact fast

Helping at home

Read each box aloud. Your kid shows the fact on one hand, says the answer, and writes it. Do the box again a day later: the answer should come faster each time.

If your kid gets stuck

Show it on one hand. Say it without counting.
