C´est WOW

Arches are very stable geometric shape. For this activity, the student will build a paper arch with building blocks called trapezoidal prisms, which he will make himself.

With only 3 pieces of cardboard, students will design their own art object, remarkable not only for its appearance, but also by all that it will allow them to learn, by making and observing it. Notions of space and shapes, of positive and negative volume; fractions and symmetry.

Cylinders are found in all kinds of musical instruments. With this activity, you will create your own original sounds by transforming glasses of water into musical instruments. Will the instrument be called a 'glassophone'?

The purpose of this activity is to create a life-size 'treasure hunt' by drawing the map of your apartment, house, garden, or a small green space next to your home like a park. Invite a friend to play with you. Let's go!

For this activity, we build a pan flute with plastic straws.

Food gives us strength and it's not just about vitamin content. In this activity, we will test the stiffness of spaghetti (before cooking, of course) and the elasticity of marshmallows. An experiment to help figuring out how to build the tallest and most solid structures.

Tangram is an ancient Chinese puzzle game. His Chinese name means 'The seven planks of cunning'. Each game is made of seven pieces. In this project, you will learn basic geometry by making your own Tangram game. Then you'll have to create two geometric shapes.

Are all bubbles spherical? In this activity, we will produce geometric bubbles of surprising shapes. Let's start with a tetrahedron, which is a volume formed by four equilateral triangles.

In this activity, we discover that the geodesic domes are incredibly solid structures. The secret of their solidity? The triangles. Triangles are shapes that are rigid and indeformable. This means that domes can be created from very light materials, such as straws, bamboo... or rolled papers.

For primary cycles 1, 2 and 3, this document accompanies activity sheets _C'est wow!_ on geometry. It includes a few words on the _C'est wow!_ Series, information on preparation for teachers, recommended age groups, topics covered, as well as recommended subjects.
