Steps

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

    • Ask: “What number is ten more than 53?” Listen for: 63
    • Ask: “What number is ten less than 31?” Listen for: 21
    • Ask: “What number is ten more than 52?” Listen for: 62
    • Ask: “What number is ten more than 42?” Listen for: 52
    • Ask: “What number is ten more than 46?” Listen for: 56

  2. Say this: “Each row of the hundred chart has ten numbers. Going down one row adds ten.”

    Say this: “All the numbers in one column end in the same digit.”

    Say this: “Hundred chart: a chart of the numbers 1 to 100 in rows of ten.”

  3. Show: What number is ten more than 69?

    Say this: “69 + 10 = 79”

    Answer: 79

    Show: Fill in the missing number: 2, 3, ___, 5, 6

    Say this: “The numbers go up by 1 each time.”

    Say this: “3 + 1 = 4”

    Answer: 4

  4. Do this: Your child does these with you. Let them try first; help only after a real try.

    Ask: What number comes just before 63?

    Listen for: 62

    If stuck: 63 − 1 = 62

    Ask: What number comes just after 7?

    Listen for: 8

    If stuck: 7 + 1 = 8

    Ask: What number comes just after 15?

    Listen for: 16

    If stuck: 15 + 1 = 16

    7 more practice items on the lesson page, and on Worksheet A and Worksheet B.

    • Thinking down one row adds one.

  6. Cover a number on the hundred chart with a coin. Your child names the hidden number and the numbers above, below, before and after it.

  7. Say this: “Tell me what you learned today. Show me with your hands or the counters if you like.”

    Listen for: Find numbers on the hundred chart.; See patterns in the chart.

  8. Count to 100 by tens and by ones (a little further each week). Count by twos to 20 and by fives to 50.
