1. Functional Mathematics Problem solving with decimals
Aims:
Use efficient and accurate methods to solve contextualised problems involving money/decimals
Learning outcomes:
By the end of the lesson ALL learners will be able to:
Read, write and understand decimals up to two decimal places in practical contexts. (as: common measures to one decimal place, e.g. 1.5m; money in decimal notation)
carry out simple calculations involving money.
identify the correct mathematical procedures needed to solve problems
Some learners will be able to (differentiated outcomes for more able learners within the group):
Carryout the calculations efficiently and accurately.
Calculate cost of credit on loans and hire purchase.

2. …understand place value & decimals
used most commonly in:
• money – for example, a tee-shirt may sell for £12.75
• weights and measures – for example, a bag of
potatoes weighs 1.5 kilos.
The number to the left of a decimal point is the ‘whole number’;
the number to the right of a decimal point is the ‘decimal fraction’.

3. Place value
Where we place a number affects its value. This is called place value, and it’s important for understanding decimal numbers.

4. the column on the right is the ‘units’ column
the column on the right is the ‘units’ column. These are numbers between 0 and 9
the next column from the right is the ‘tens’ column. These are 10, 20, 30, 40, 50, 60, 70, 80, 90
the third column is the ‘hundreds’ column. These are the hundreds from 100 to 900.

7. Money Problem Solving Show all your working out – you can use a calculator
1) 4030 people go to a football match. Each ticket costs £4.25.
What is the total cost of all the tickets?
2) A person earns £345 per month.
What is his annual salary?
3) You pay £ in tax per year.
How much do you pay per month in tax?

4) Arnis pays £58.50 per week in rent.
How much does he pay per year?
5) Sale items were advertised at half price of normal prices.
What did it cost in a sale to buy a blouse, skirt and jeans if the normal prices were £17.60, £19.40 and £14.40 respectively?
