  1. STUDY LIST

  2. Whole Numbers Topic • Place Value • Write numbers in words and vice versa • Rounding to the nearest 10,100 • Addition & Subtraction (including mixed) • Multiplying by 10,100 and 1000 • Short & Long Multiplication • Dividing by 10,100 and 1000 • Short & Long Division • BIDMAS

  3. Place Value Learning objective: Can I identify the place value of the underlined digit?

  4. PLACE VALUE • 1 265 • 2 145 = tens = hundreds

  5. Numbers in words & vice versa Learning objective: Can I write a number in words and vice versa?

  6. PLACE VALUE 1 265 2. Thirty five thousand, two hundred and forty = one thousand, two hundred and sixty five = 35, 240

  7. Rounding to the nearest 10,100 Learning objective: Can I round numbers to the nearest 10,100 and 1000?

  8. Nearest 10,100 25 to the nearest 10 582 to the nearest 100 = 30 = 600

  9. Addition Learning objective: Can I add numbers without using a calculator?

  10. Adding • 57 + 35 2. 365 + 478 = 92 = 843

  11. Subtraction Learning objective: Can I subtract numbers without using a calculator?

  12. Try these: • 52 – 25 2. 124 - 89 = 27 = 35

  13. Multiply & Divide by 10,100 & 1000 Learning objective: Can I multiply and divide by 10, 100 and 1000?

  14. Multiply, Divide by 10,100 & 1000 • 23 × 10 • 256 ÷ 100 • 24 ÷ 1000 = 230 = 2.56 = 0.024

  15. Multiplication Learning objective: Can I multiply numbers without using a calculator?

  16. SHORT MULTIPLICATION 64 × 9 = 576

  17. LONG MULTIPLICATION 74 × 39 = 2886

  18. Division Learning objective: Can I divide numbers without using a calculator?

  19. The “bus stop” method You do need to know your tables! The most common method is called “the bus stop”, because it looks like the numbers are waiting in a bus stop. The divisor goes outside the “bus stop”. You can also add multiples of your divisor, but this will take you longer!

  20. Calculate these, without a calculator! • 168 ÷ 7 • 223 ÷ 6 • 384 ÷ 12 • 954 ÷ 17 = 24 = 37 r 1 = 32 = 56 r 2

  21. More on LONG DIVISION • 684 ÷ 19 • 435 ÷ 25 = 36 = 17 = 17 r 10 = 17.4

  22. BIDMAS Learning objective: Can I use BIDMAS?

  23. Mixed Sums & BIDMAS • 265 – 25 + 121 - 12 • 350 – 400 + 75 – 23 • 2 + 3 x 4 • 25 ÷ 5 + (4 - 3) = 349 = 2 = 14 = 6
