## Ready when they can

- Calculate 23 × 4 using partitioning (20 × 4 + 3 × 4)
- Calculate 96 ÷ 8 using known table facts
- Begin to use a formal written layout for short multiplication

## Lesson: Multiplying and Dividing Bigger Numbers

Priya's array showed how 2 × 5 = 10 tells the story of rows. Party bags need bigger stories, like 23 × 4 treats or 96 sweets shared as 96 ÷ 8. The trick for multiplying is to split the big number into tens and ones, work out each piece, then add the pieces back together.

*(drawing: 4 rows of 3 make 12. That is the small piece you need for 23 × 4, because 23 has a 3 in the ones place.)*

**Example.** To work out 23 × 4, split 23 into 20 and 3. First, 20 × 4 = 80. Then, 3 × 4 = 12. Add the two parts: 80 + 12 = 92. So 23 × 4 = 92.

Grown-ups often write multiplication in columns, like a small tower of numbers. You multiply the ones digit first, write down the ones part of the answer, and carry any tens into the next column. It looks different, but it does the same job as splitting the number.

*(drawing: 96 sweets split into 80 and 16. Each part shares cleanly into groups of 8.)*

**Example.** Division uses your table facts too. To work out 96 ÷ 8, ask: what times 8 makes 96? You know 8 × 12 = 96, so 96 ÷ 8 = 12. If that feels too big, split it: 96 is 80 + 16. 80 ÷ 8 = 10 and 16 ÷ 8 = 2, so 10 + 2 = 12.

**Recap.** Split big numbers into tens and ones, multiply or divide each part with your tables, then put the parts back together.
