Adding, subtracting, multiplying, dividing decimals

What you'll learn

1. 1

   Think of a £5 note. You split it into 10 equal bits — each bit is 10p, or 0.1 of the whole note.

2. 2

   If you cut a £1 coin into 10 equal bits, how much is one bit worth?

3. 3

   Use these money bits to show 0.3 + 0.4. Drag the coins to add them together.

4. 4

   Let's do 0.6 × 3 together. That means 0.6 + 0.6 + 0.6.

5. 5

   What is 0.7 × 2?

6. 6

   Now try 1.2 ÷ 3. Use the bar model to split 1.2 into 3 equal parts.

7. 7

   What is 0.8 ÷ 4?
