Geometric shapes

After this understanding work, offer the students a second viewing with a task to carry out: locate and name the geometric shapes present in the video.

Figures: circles or discs (top of the birthday cake, clock, moon, sewing machine wheel, gas stove buttons), five or six-pointed stars, diamond (on the door, on the wall in the kitchen area), triangles (pennants), rectangles (calendar, paintings, building windows, workshop gate)...

Solids: cones (birthday hats), paving stones (cardboards in dad's workshop, books, steps of the staircase), spheres (lanterns in front of the workshop gate, the planets, the earth, astronaut helmet), half sphere (light fixture), cylinders (the cake, the university building)...

Depending on the skills we want to work on, we will focus on plane figures, or solids, or both (with a sorting activity). In the same way, we can ask students to list and name the shapes present in the class. If possible, offer them manipulative materials so that it is more concrete for them. The shapes thus studied can be reproduced in a visual art project: representing a spatial universe.

We can offer students:

• to trace figures in their drawing using the ruler, the square and the compass for the plane figures (a circle with the compass for the planets, a rectangle then a triangle with the ruler and the square for the rocket, etc.)
• to carry out production in 3 dimensions if we want to work on solids, which will be an opportunity to manipulate patterns.
