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.

Whole-part models
1.245 3.7651.245
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 = ?

We will need to add our two
answers together to find the
answer.
1.076 + 2.903 =
We will need to subtract the smaller
number from the larger number to
find the answer.
2.903 - 1.245 =

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.
