Presentation
- Directress has the child find one bingo tile to match all the dividends along the top of Chart II.
- These are placed in a box cover.
- The child fishes for a tile, i.e., 24.
- Directress says: "Let's try to find all the quotients with zero remainders that can be made with this dividend".
- Start with 24 ÷ 9 =.
- It won't work so leave it blank, and go on24 ÷ 8 = 3 and so on with the child giving the correct quotients.
- At the end erase those that would not yield zero remainders, thus leaving space to correspond with Chart I.
- Notice how the column of quotients matches the column under 24 on the chart.
- Directress says to the child: "These are the combinations I wanted, because now we can do 3 x 8 = 24".
- Write this to the right of 24 ÷ 8 = 3. 24 was my dividend: now it is my product.
- Go on in the same way for the other combinations making a second column.
- The child will realize that if 24 ÷ 8 = 3, then 24 ÷ 3 = 8.
- It is a sort of game where the numbers change positions.
