The sixth programme provides a focus for weight and money. The listeners are also aware of the passage of time.

Broadcast date: 24 November 2006

Story outline: In today's programme, Dylan the DJ is joined in the studio by a French chef - 'Madame Le Saucepan.' Rhoda has the day off, but is persuaded by Dylan to help shop for a variety of ingredients which are needed for the cookery demonstration. Jamie joins Rhoda in the supermarket and helps her to calculate both the weight and cost of the ingredients. Madame Le Saucepan insists on starting her cooking at noon. Will there be enough time?
Key Stage 1: Measures, Number Pupils should have opportunities to:- know the most commonly used units in weight, (including kilograms) and use them to measure in purposeful contexts; add and subtract money; use these skills in problem solving situations.

Key Stage 2: Measures, Number Pupils should have opportunities to:- understand the relationship between units in measurement; convert from one metric unit to another; use the four operations to solve problems; estimate and approximate to gain a feeling for the size of a solution to a problem before carrying out a calculation.

Learning outcomes:
  • Pupils will develop their skills of mental mathematics in the four operations.
  • Pupils will appreciate that weight can be given in grams or kilograms.
  • Pupils will calculate the cost of items and determine those which represent best value.
  • Pupils will estimate shopping totals.
  • Pupils will calculate the passage of time.
Mental Maths:

Rhoda and Jamie have only twenty minutes to shop and bring the ingredients to the studio.
  1. Pupils should discuss what activity they could carry out in twenty minutes.
  2. How long would it take them to go to the nearest shop, buy three items and return to school?
  3. Write the following amounts on the blackboard, (it may help to present the list vertically):- £1.50, £0.62, £1.90, £0.30, £2.70. Ask the pupils to quickly estimate the total. Cover the list after ten seconds.
  4. Discuss personal methods of making it easier to get a rough estimate.
  5. Using a bag of sugar as a known weight, can the children estimate the weight of at least six other objects? Working in pairs will help to develop the language of weight.
Points for Pupils to Ponder:

Rhoda has five coins in her pocket. They come to a total of £1.22. I wonder what the five coins could be. How many different possibilities are there?

Put three coins in your pocket. Can your partner work out what coins are there by asking not more than eight questions? You are only allowed to answer Yes or No.
