Starter Hello, year 5!

Your starter activity today is to revise area. Please log into

your Education City account and you will find the following

activities for you to complete in this week's maths folder.

LO: to solve problems involving numbers

with up to three decimal places.

0.3 0.9

1.2 1.7

4.35

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.

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 = ?

We will need to add our two

answers together to find the

1.076 + 2.903 =

We will need to subtract the smaller

number from the larger number to

find the answer.

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.

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.
