  1. Multipling x 1000

  2. Multiplying x 1000 If we have : 1000 +1000+1000=………. = 1000 x 3 1000x4=1000+………+………+……… =……… By the same way: 34x1000=34000 3000 1000 1000 1000 4000

  3. complete: 8000 8 • 8x1000=1000x……=……… • ……x1000=1000x……=7000 • 2x3x1000=…….x1000=……… • 3x……x1000=……x1000=9000 • 5x……x1000=1000x……=35000 7 7 6 6000 9 3 35 7

  4. Complete : 8 800 • 20x40=100x……=……… • 30x50=…….x100=……… • 6x200=……x100=……… • ……x100=…….x1000=9000 • ……x10=35x100=……… 15 1500 12 1200 90 9 350 3500

  5. As you know ,one kilogram=1000 grams .complete • 3 kilograms=………grams because 3x1000=……… • 14 kilograms=………grams because 14x1000=………… 3000 3000 14000 14000

  6. Multiplying a 2-digit number by a 1-digit number

  7. Example: 1 1 6 2 3 4 X 3 6+1 9+1 12 1 8 7 0 2

  8. 1 1 9+1 6+1 12 6234 x 3 = 18 7 0 2 Note: The vertical product = the horizontal product .

  9. Multiply: 2 3 5 6 X 4 5 4 2 3 X 8 9 4 2 4 4 3 3 8 4

  10. Find the product: 1300 325 x 4 = ……… 452 x 5 = ……… 783 x 2 = ……… 1235 x 3 = ……… 1432 x 6 = ……… 2260 1566 3705 8592

  11. Unit Two Division

  12. Finding the quotient • Ahmed has 10 rabbits. He wants to put 2 rabbits in each box. How many boxes does he need ? We can divide to find how many boxes he needs : divisor 10 ÷ 2 = 5 quotient dividend

  13. Note that .. There are three ways to express the division operation. For example : To divide 12 by 4 , you can write : 12 ÷ 4 = 3 3 12 = 3 4 or 12 4

  14. Exercises .. • 42 ÷ 6 = ……… (2 , 4 , 6 or 7) • 20 ÷ 5 = ……… (4 , 5 , 15 or 25) • 56 ÷ 7 = ……… (5 , 6 , 7 or 8) • 9 ÷ 9 = ……… (9 , 1 , 0 or 18) • (12 ÷ 3) + 1 = ……… (4 , 5 , 3 or 10)
