Description of the activity:

Introduction

One of our classmates called Maria is turning 12 next week and we have decided to make a party.

Organization of the class: we will make groups of four.

 Procedure

We are going to design some chart shaped cards, in which we will present the children to different supermarkets and toy stores. These charts contain three different toy stores with different items. The same item is going to be sold in each store but at different price. They will have to buy a present and make a cake, so they will have to select the ingredients among different supermarkets and they only have £20 budget for each group.  

Step one- We will have to divide the class in groups of four. Children must make a shopping list and get three items from the supermarket and choose a present from the toy store. 

Step two – Children will need to buy the items in different supermarkets and stores in order not to exceed the budget proposed and get the cheapest price.

Step three- With the different items selected from the supermarkets, they will have to make a cake with eggs, flour, oil or butter, and jam.

Step four- They will have to select a present from a toy store, depending on remaining budget.

Step five- Finally, they will have to explain in groups what items they have chosen, specifying where they were bought.  We will check the calculations on the blackboard.

Assessment

The teacher must play the role as a simple observer, supporting and giving the necessary feedback, especially with the spelling of difficult words.

In this type of activities, it is important to evaluate different aspects, team work and individual work, pronunciation, etc.  For this purpose, we are going to use the following chart:

	Low learning	Average learning	Good learning	Excellent job	Marks
Individual work
Pronunciation
Intonation
Group work
Organization

Estimative scale	Low work	Average Knowledge	Good Learning	Excellent job
Total score	1-5	6-10	11-15	16-20

I hope you enjoy the idea.
