When cooking we can observe the relation to geometric shapes, from the moment we pick up a container, open a bag, cut fruit or prick olives with chopsticks, we maintain a constant relationship with geometry.
For example, to make a sandwich we need 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, which 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 a sandwich in half, that means, cutting it from edge to edge, which will give us two triangular prisms. With this simple operation, we will study the base, the faces, the height, the vertices and the edges.
If we ask our students to cut it in half again, we obtain four triangular prisms that allow us to form different figures: for example, a pyramid, different types of quadrilaterals (a rhombus, a rhomboid), different types of isosceles triangles, as well as many other figures by joining the vertices, the sides, etc.
In this way we work on the content in a more dynamic, practical and fun way, which may capture the attention and interest of the students.
But this is not the only way we can approach geometry in the kitchen, there are many ways of doing it, for example by using vegetables and fruit, irregular foods that are transformed into regular figures thanks to the arrangement by combining, for example, different cuts to obtain concentric circles, ellipses, rhombuses, pentagons or any other shape.
