About this chapter
Split a number to make a hard table easy: 5 × 15 = 5 × 10 and 5 × 5 = 50 + 25 = 75. An even number can be halved: 6 × 14 is double 6 × 7 = 42 + 42 = 84. Multiplying by 10 gives tens — 26 × 10 = 26 Tens = 260. Multiplying by 100 gives hundreds — 27 × 100 = 27 Hundreds = 2700. 10 tens make 1 hundred and 10 hundreds make 1 thousand. To multiply two big numbers, split both by place value and add the small products: 15 × 14 = 100 + 40 + 50 + 20 = 210. To divide, take away equal groups again and again. What is left at the end is the remainder .

Quick revision
| Idea | What we do | Example | Answer |
|---|---|---|---|
| Splitting a table | Break into 10 and the rest | 7 × 15 = 70 + 35 | 105 |
| Doubling | Halve, multiply, double | 6 × 14 = 42 + 42 | 84 |
| Times-10 | Count in tens | 38 × 10 = 38 Tens | 380 |
| Tens times tens | Use 2 Tens, 3 Tens … | 13 × 30 = 39 Tens | 390 |
| Times-100 | Count in hundreds | 53 × 100 = 53 Hundreds | 5300 |
| Bundling | 10 hundreds = 1 thousand | 10 × 100 | 1000 |
| Grid multiplication | Split both numbers by place | 64 × 152 | 9728 |
| Dividing by 10 | How many tens? | 870 ÷ 10 | 87 |
| Dividing by 100 | How many hundreds? | 600 ÷ 100 | 6 |
| Division with remainder | Take away equal groups | 324 ÷ 14 | 23, remainder 2 |
| Half and double | One halves, other doubles | 44 × 10 and 22 × 20 | both 440 |
| Teen pattern | 1 | sum | product of ones digits | 12 × 13 | 156 |
