Geometry in our sandwiches

Hello everyone!!

Today we continue to discover more about geometry, but we will focus on how in the kitchen geometry is part of our lives, as when cooking we make complex relationships of geometric shapes, such as when we are making a sandwich, students can form multiple geometric figures.

In addition, thanks to this area we work with geometric shapes, we can work with the pupils about different skills such as linguistic communication skills, interacting with other classmates, presenting their creations and working individually and collaboratively (learning to learn), with a sense of initiative and entrepreneurial spirit (it encourages creativity and the ability to take risks and plan in terms of the creation of geometric shapes and figures, the appreciation of the colours of food and their perception according to their planes and space).

We are also establishing a more dynamic, practical and participatory teaching-learning process, encouraging interest in the subject.

When cooking we relate to geometric shapes, from the moment we pick up a container, open a bag or cut an onion, we maintain a constant relationship with geometry. For example, making a sandwich requires two slices of sliced bread, which are two rectangular prisms, also known as orthohedrons.

It is not the same to explain to our students that we are going to study orthohedra as to say that we are going to study the shapes of a slice of sliced bread, whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel and equal rectangles two by two.

If we want to use sliced bread as a model to study geometry in our classes, we can ask them to cut the bread into a sandwich, starting from the base. in a sandwich by cutting it in half, or cutting it from edge to edge, which will give us two triangular prisms. With this simple operation, we will obtain: study the base, the faces, the height, the vertices and the edges.

See you soon in the next blog! 😊
