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

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

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

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

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

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

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

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

Adding 1. 57 + 35 = 92 2. 365 + 478 = 843

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

Try these: 1. 52 – 25 = 27 2. 124 - 89 = 35

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

Multiply, Divide by 10, 100 & 1000 1. 23 × 10 2. 256 ÷ 100 3. 24 ÷ 1000 = 230 = 2. 56 = 0. 024

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

SHORT MULTIPLICATION 64 × 9 = 576

LONG MULTIPLICATION 74 × 39 = 2886

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

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!

Calculate these, without a calculator! 1. 168 ÷ 7 = 24 2. 223 ÷ 6 = 37 r 1 3. 384 ÷ 12 = 32 4. 954 ÷ 17 = 56 r 2

More on LONG DIVISION • 684 ÷ 19 = 36 • 435 ÷ 25 = 17 r 10 = 17. 4

BIDMAS Learning objective: Can I use BIDMAS?

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