Search for Quotients

Age
7-9.

Materials

 * Chart II
 * Bingo tiles for multiplication

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.

Purpose
Directs Aim:


 * &lt;span id="fck_dom_range_temp_1246510733062_432" /&gt;To find quotients with zero remainders.
 * To realize the relationship between multiplication and division memorization of division

Indirect Aim:


 * Preparation for the divisibility of numbers
