Preparation


Presentation

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