LO: to solve problems involving numbers with up to three decimal places. 0.3 0.9 1.2 1.7 4.35

SLIDE 3

In order to answers these types of calculation, we will have to practise two key skills.

Key skill 1:to add and subtract decimal numbers. Key skill 2:to solve worded problems involving decimals.

1.245 3.765 1.245 3.765 In this instance, we know we need to add the two decimal numbers together to find the answer: 1.245 + 3.765 = ? This time we will need to find the missing number from our calculation: 1.245 + ? = 3.765 We will therefore use the inverse 3.765 - 1.245 = ? 5.01 2.52

Key skill 2:to solve worded problems involving decimals. I had £54.69 in my purse. I went shopping and bought a new pencil case for £2.98, a box of chocolates for £4.50, a fizzy drink for 65p and a sandwich for £2.75. How much money did I have left in my purse? What must we remember to do to ensure accuracy? How many steps will we need to make?

Key skill 2:to solve worded problems involving decimals. We must remember to line up the decimal point to ensure that we add

accurately. This is a two-step problem.

Add up the amounts of the items bought. Subtract this amount from the amount in the purse.
