Steps

  1. Do this: Ask these out loud. Your child answers out loud; no paper needed.

    • Ask: “3 + 2” Listen for: 5
    • Ask: “7 + 4” Listen for: 11
    • Ask: “1 + 9” Listen for: 10
    • Ask: “5 + 9” Listen for: 14
    • Ask: “8 + 5” Listen for: 13

  2. Say this: “Measure by laying units end to end with no gaps and no overlaps.”

    Say this: “The length is how many units fit.”

    Say this: “Unit: the same-size thing used again and again to measure.”

  3. Show: Which is longer, A or B?

    two objects to compare

    Say this: “Both start at the same place. Compare the ends.”

    Say this: “B is longer.”

    2 by 1 grid

    Say this: “Count the squares from one end to the other: 1, 2 … 2.”

  6. Call out a time to the hour or half hour. Your child sets a paper clock. Then swap: your child calls and you set it.

    Listen for: Measure length with equal units.

  8. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

    Genesis 1:5 (KJV)

    God made day and night. Clocks help us keep track of the hours He gives us.

  9. Say the hours around the clock face. Each day ask “What time is it?” at an hour or half hour.
