5. Division Charts 1 and 2

#### Material

Chart 1, showing all the answers for the tables.
Chart 2, blank for receiving answer tiles.
For each chart, a set of division combinations (tickets) without the answer.
For each chart, a receptacle for completed problem tickets.
For Chart 2, a box of square wooden tiles with the answers.
Squared paper, pencil.

#### Presentation

##### Division Chart 1
1. Invite the child to the lesson.
2. Introduce division chart 1.
3. Ask the child to bring the materials to a table.
4. Talk about the numbers.
5. “These numbers at the top are what we start with, we are going to share them out. These numbers over here are what we share out by.”
6. Give an example such as 14 ÷ 7
7. Place your dominant finger on the number at the top, such as 14
8. Place your subdominant finger on the number on the side, ÷7
9. Slide your dominant finger down and your subdominant finger to the right until they meet in the box that says 2.
10. “There’s the answer!”
11. Demonstrate once more with two different numbers.
12. Give the child a couple examples to do.
13. Bring a paper, pencil, and underlay on a tray.
14. Open the box of prepared slips.
15. “Go ahead and pick a random card.”
16. Wait for the child to pick a card.
17. Ask the child to read it.
18. Ask the child to write the problem on his paper.
19. Ask the child to use the chart to find the answer, and to write it on his paper.
20. Sit with the child for a couple more examples, then let him work independently.

#### Division Chart 2

1. Invite the child to the lesson.
2. Show him division chart 2.
3. Ask him to bring the material to a table.
4. “We don’t need paper or pencil this time.”
5. Look at the chart with the child.
6. “There are no numbers here.”
7. Open the box of tiles.
8. Organize them in a row from 1 through 9.
9. Ask the child to help you; once completed there will be 9 rows of 1 through 9 making a square.
10. Open the box of slips and pick a slip, read it, and solve it. Isolate the tile, then use the board to figure out where it goes.
11. Place the tile in its spot on the chart.
12. Stay with the child as he solves a few problems, then let him work independently.

#### Exercises

Child works independently.

#### Purpose

Memorization of division combinations.

#### Control of Error

Division Chart 2 uses Division Chart 1.

5 1/2 to 6 1/2

#### Note

If the child asks about the numbers at the top of the chart that are white, you can say “These numbers up here that are white instead of blue are called prime numbers. That means they can only be divided by 1 and themselves.”
