Problems involving 'real life' money or measures.
Give the children a simple shopping list and ask the children in pairs to write down the page numbers where you would find the items and their prices.

Solve word problems involving numbers in 'real life', money and measures, using one or more steps.
a) Tell the class that the supermarket is offering a two for one deal on their own brand lasagne. How much is the equivalent price now of one lasagne? Repeat for a three for two deal.

b) Give the class a shopping list. In pairs, ask the children to find the products, write down the prices and give you the total bill.

Use all four operations to solve word problems involving numbers in 'real life' money and measures using one or more steps.
a) Compare own brand sausages with a more expensive brand. Per gramme, which brand is more expensive and by how much? Why do you think this is?

Relate fractions to division.
Explain that as a special promotion for this month all frozen chips are reduced by one third. What are the special offer prices?

Begin to understand percentage as the number of parts in every 100, and find simple percentages of small whole number quantities e.g. 25%.
On two sizes of the same shampoo explain that the supermarket is offering 25% extra free on the smaller bottle. Is it now cheaper to buy two smaller bottles or one large bottle? What price does it work out per gramme, per 10g, per 100g?

Use all four operations to solve simple word problems involving numbers and quantities based on 'real-life' money and measures.
Explain that you want to make a special cake for a friend's birthday. On the board list the ingredients you will need and ask the class to cost the cake for you. Extend this by asking how much each slice would cost if you cut it into six/eight/ten slices.

Understand percentages as the number parts in every 100.
Tell the class that a rival supermarket doesn't charge the £4 delivery fee but their prices are 5% higher. Give the class a shopping list and ask them to decide which supermarket is better value.

Identify and use appropriate operations to solve word problems involving numbers and quantities.
Write a recipe on the board. Explain that this serves two people. Ask them to cost it and then cost it again for three people. This is a difficult practical problem as they may need to buy more than they need as soon as you cannot buy half a packet. Smaller packets may also cost relatively more than a larger packet.
