Kindergarten math · Unit 9: Measuring

Line up the ends

What this lesson shows

Two pencils with their ends lined up: the blue one is longer, and the red one is shorter.

The worked example

The lesson works this one step by step: pencils, 8 and 4: which is longer. Then your kid tries one like it on paper.

The steps

  1. Line up one end
  2. Look at the other end
  3. Farther: longer
  4. Not as far: shorter

Helping at home

Read each box aloud. Then compare real things: two spoons, two shoes. Your kid lines up one end first, then looks at the other end.

If your kid gets stuck

Line up one end. Look at the other end.
