Exercise 33. Drill Cards for Division

1. Cut a cardboard strip 5 inches by : D E

inch. 8 18 2. On one side put Drill D and on the other 64 72 side Drill E as shown in the picture at the left. 48 36

3. Divide each number in Drill D by 2, by 16 54

4, by 8. 72 126 24 162

4. Divide each number in Drill E by 3, by 88 144

6, by 9. 32 108

6. Prepare a drill strip for numbers which 80 180 contain 5 a whole number of times. 40 90

6. Prepare a similar strip for 7. After the pupils have practiced on the cards with the numbers as indicated, other cards may be made containing a series of numbers such as 48, 54, 30, 72, 16, 24, 40, 60, 56, 12, 32, 45, 36.

After drilling with cards that are exactly divisible by 2, 3, 4, 5, 6, 7, 8 or 9, use numbers that will give remainders. For example 15; 9; 23; 46; 29; 52; etc., divided by 7. Express the remainder in the fractional form (1).

Exercise 34. Short Division

1. Divide 3024 by 7.

Explanation: 7 is not contained in 3 432 quotient (thousands). Change the 3 thousands to

hundreds, making 30 hundreds. 30 (hunDivisor 7)3024 dividend dreds) contains 7, 4 (hundred) times, leav

ing a remainder of 2 (hundreds). Place the 4 in the hundreds' place in the quotient and change the remainder 2 hundreds to tens, making 20 tens. 20 tens + 2 tens make 22 tens. 22 (tens) contains 7, 3 (tens) times with a remainder of 1 (ten). Place the 3 in the tens' place in the quotient and change the remaining 1 (ten) to units, making 10 units. 10 units + 4 units make 14 units. 14 contains 7, 2 times.

Place the 2 in the units' place of the quotient. 2. Katherine, Ruth

Ruth and Henry earned $2.10 from a lemonade stand. How much did they each earn if they divided their profits equally?

3. There are 365 days in a year. This is how many weeks of 7 days each?

4. Nine children together gave $5.40, which they had earned, to the Fresh Air Fund. What was each one's share if they contributed equally to the fund? 5. 4)6024 6. 5)7580 7. 3)6456 8. 6)2736
