1. Be inspired by the Great British Bake Off. Choose a cake recipe and get the children to make a list of ingredients. If necessary, go with them to the shops to buy the ingredients. They must calculate the total of any items they need to buy and they must hand the cash over and work out any change. When making the recipe check that they can read the numbers correctly for the measurements given in the cookbook then allow them to weigh out the ingredients. If you want to stretch them further think about doubling the recipe and having them work out the new measurements. Once the ingredients are prepared and the cake is ready to go in the oven have the children set the timer (do double check though after each step of the process). Then have them work out the time an ordinary clock will show when the cake is baked. The final task is to work out how many people will be eating the cake or cakes or and give the children the job of accurately dividing the cake or cakes up so that everyone gets an equal share.
2. Using an online route planner, plan a dream trip to a location of your choosing with various stop-off points on the way. Choose a method of transport and select two or three different route options. Print off the results. Have your children calculate the distance and time for the various route options by adding together the mileage and time for each section of the journey. Now ask them to work out which route would be the shortest, the longest, be the cheapest and so on?
3. If you go out for ice-cream or some other sort of treat then give your child the responsibility of taking the orders for food and drink. Have them write down the items and their cost and then do a written calculation of the total. Give them some money – a mixture of notes and coins and then ask them to write down the denominations and total the budget you have given them. Now ask them to place the order and pay for it themselves and check any change they are given is correct.
4. If you are travelling in a car then have the children choose a car number plate. Tell them that each letter on the number plate equals its place in the alphabetic order – A=1, B=2, C=3 etc. They should write the number plate down and then calculate the numerical value of the number plate mentally then have them check the answer is correct by writing down the sum and working it out. If you really want to stretch them have the alphabet reversed and make Z=1, Y=2 and X=3.
5. If you have a pack of playing cards handy divide them into two groups – the first pile should contain all the playing cards numbered 6 and higher. The jack should be valued as 11, the queen =12 and the king = 13. The second pile contains all the remaining cards from 5’s down to the ace which equals 1. Each participant gets to choose three cards from each group. They then add the three cards from the first group of high cards together and from the total subtract the sum of the three cards from the second group (the lower cards). For multiple players award the person with least difference 5 points. Have one child keep score. Shuffle the cards between each player’s turn.
