L.Obj: to work a budget, surface areas and distances

L.Obj: to work a budget, surface areas and distances What maths do you use doing your Christmas Shopping?

L.Obj: to work a budget, surface areas and distances What else do you have to consider?

L.Obj: to work a budget, surface areas and distances Your task this Christmas is to help Jack choose, wrap and deliver 6 presents to his friends and family. There are three tasks. Where should I go first? What shall I buy? How Much have I got left? How Much wrapping?

L.Obj: to work a budget, surface areas and distances Task 1 He has decided that each person has to have one of two presents that they will LOVE to open on Christmas Day. You must decide which of the two presents to buy for each person, but you have a budget of only £140 to use in total.

L.Obj: to work a budget, surface areas and distances You can choose either of the two presents. Be careful! Jack has only £140 in his piggy bank to spend, which includes wrapping paper!

L.Obj: to work a budget, surface areas and distances Task 2 The presents need to be wrapped up! You need to calculate the number of rolls of wrapping paper that will be needed. There is a choice of paper, each roll has a different price. You do NOT have to use the same paper for each present.

L.Obj: to work a budget, surface areas and distances The six presents all need wrapping paper! There are 4 designs to choose from, and each costs a little bit more or less. Remember you have a total of £140 for presents and paper, so choose the paper wisely!

L.Obj: to work a budget, surface areas and distances Harry is getting a PS2 game (His mum couldn’t find a PS3) Width 15 cm Depth 2 cm Height 12 cm The box needs unfolding along its two shorter lengths to make the most efficient wrapping. Height 12 cm (twice) Depth 2 cm (twice) Folds 5 cm (for joins) 38 cm of paper All presents need 5 cm for joins! You cannot wrap one present with two different types of paper.

L.Obj: to work a budget, surface areas and distances Task 3 Jack’s Mum has told him that he must be back in as short a time as possible. You need to plan the most efficient route for the delivery of presents. On the evening of delivering the presents it is cold and snowing!

L.Obj: to work a budget, surface areas and distances Your journey starts and ends at home (Jack’s house) And must pass each of the places to deliver the presents. Use the scale to find out exactly how many metres Jack will need to travel.

L.Obj: to work a budget, surface areas and distances As usual, you will need to set out YOUR solution by way of a poster on A3 paper.
