Lesson 2.1 Counting On

Steps

1. Warm-up

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

   • Ask: “0 + 0” Listen for: 0
   • Ask: “6 + 6” Listen for: 12
   • Ask: “9 + 3” Listen for: 12
   • Ask: “2 + 1” Listen for: 3
   • Ask: “3 + 2” Listen for: 5
2. Teach the new idea

   Say this: “To add 9 + 3, start at 9 and count on three: 10, 11, 12.”

   Say this: “Always start with the bigger number. 2 + 8 is easier as 8 + 2.”

   Say this: “Count on: start at one number and count up.”

3. Show how

   Show: 5 + 8 = ___

   Say this: “Make ten: 8 needs 2 more to make 10.”

   Say this: “Split 5 into 2 and 3.”

   Say this: “8 + 2 = 10”

   Say this: “10 + 3 = 13”

   Answer: 13

   Show: The baker made 11 rolls and 8 loaves. How many pieces of bread did she make?

   

   Say this: “Unknown: the total.”

   Say this: “Bar model: two parts, 11 and 8; the whole is unknown.”

   Say this: “Equation: 11 + 8 = ?”

   Say this: “11 + 8 = 19”

   Say this: “Answer: She made 19 pieces of bread.”

   Answer: 19 pieces. She made 19 pieces of bread.

4. Practice together

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

   Ask: 8 + 4 = ___

   Listen for: 12

   If stuck: Make ten: 8 needs 2 more to make 10.

   Ask: 4 + 6 = ___

   Listen for: 10

   If stuck: 4 + 6 = 10

   Ask: 5 + 6 = ___

   Listen for: 11

   If stuck: Make ten: 6 needs 4 more to make 10.

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

5. Watch for
   • Counting the starting number as one of the jumps.
6. Game: Doubles War

   Each player turns a card 1–10 and says its double. The bigger double wins both cards.

7. Narration

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

   Listen for: Add by counting on from the bigger number.

8. Scripture

   There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.

   Two and two: doubles were the order of the day on the ark.

9. Daily habit

   Recite the doubles (1 + 1 to 10 + 10) every day, then the make-ten pairs.

2. Session 2. Warm-up again, then show how with the examples.
3. Session 3. Practice together, then play the game.
4. Session 4. More practice on the worksheet, and the daily habit.
5. Session 5. Quick check: narration and a few practice items. Move on when it is mostly right.
