### Age

3-6

### Materials

- Division Board.
- 81 Green beads.
- 9 Green Skittles.
- Division tables to work.
- Summary of division tables up to 81.
- Mix sum cards (stage 1-3).

### Preparation

### Presentation

- Directress introduces the child to the Division Board and selects a division table to work with.
- For the first question, 24/9, Directress takes 9 skittles and says, "These 9 skittles represent 9 children".
- And she places the skittles along the top of the board.
- Then Directress asks the child to count 24 green beads, and asks him to divide the 24 beads to 9 children.
- At the end, the child will find that he could not divide the beads equally.
- After distributing 2 beads each to a child, the remainder 6 beads could not be divided equally.
- Hence, we move the remainder 6 beads down to the bottom of the board and explain to the child that 24 divided by 9 is equal 2 remainder 6.
- Remove 1 on the skittle and now we have 8 skittles.
- Ask the child to divide the 24 beads now.
- The child will find that each skittle (child) has 3 beads.
- Hence, 24 divided by 8 is equal 3.
- Encourage the child to work through the Division Table.

### Control Of Error

The skittles and the holes act as control of error.

### Points Of Interest

### Purpose

- Provide concrete experience of division using a divisor up to 9.

### Variation

### Handouts/Attachment
