Teaching Ideas : Kitchen Maths
You can help the children develop and practise their skills in number, geometry and measurement when working practically in a family kitchen to follow recipes, prepare foods and clean utensils and crockery.
The children can show their grasp of number calculations by getting them to add prices of different foods to match a range of budgets.
They can try dividing measurements of different foods to create recipes for groups of people. When baking the children can identify the describe the properties of shapes used when making biscuits and decorating cakes. They can also practise measuring the correct quantity of ingredients needed for a particular recipe. The children can investigate the capacities of different containers and vessels in the kitchen.
The children can use prices of foods in the kitchen cupboards to practise their number calculation skills. They can try selecting and adding prices of food needed for a favourite recipe. The children can choose foods to match a family budget by using subtraction decomposition methods. Get them to explain to other members of their family the steps used when completing a calculation to check their understanding of the addition or subtraction method. The children can also try multiplying prices of different foods in the kitchen. Get them to explain how to use facts from the times tables to support multiplication of a number.
Get the children to collect a number of different containers and vessels from the kitchen cupboards. Help them select vocabulary that can be used to describe the shape and size of the different containers and vessels. The children can estimate the capacity of each of the different containers and vessels in millilitres and litres before measuring the actual capacities using a jug with a scale. Get them to order the containers and vessels into order from the lowest to the highest capacity.
Work with the children in the kitchen to practise following recipes to make a range of family meals. Help them to measure ingredients needed when preparing a meal by using a kitchen scale. Show the children how to calibrate the scale so that it can be set at zero before measuring an ingredient. Teach them to how to count along the marked divisions on the scale so that each measurement can be read accurately. Get the children to practise converting ingredients for different family meals between different units of measurements such as from grams to kilograms.
The children can also select some of their favourite recipes to make a meal for their family. They can practise adjusting the ingredients needed for each recipe to match the members in their family. For example, when following a recipe to make a pizza suitable for two people they can multiply the ingredients by four to make enough pizzas for a family of eight. Similarly, when following a recipe to make a stew for eight people they can divide the ingredients by half to make the ingredients suitable for a family of four.
Help the children prepare and bake some biscuits for the family to enjoy. They can choose geometric shapes to use as the design for their biscuits. Get the children to identify the properties of the shapes they have selected for the biscuits in terms of their sides, vertices, angles and lines of symmetry. You can challenge the children to make as many quadrilateral shaped biscuits from the dough such as parallelograms, trapeziums and diamonds.
