几何形状

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)...

根据我们想要学习的技能，我们将重点关注平面图形或实体，或两者兼而有之（带有排序活动）。同样，我们可以要求学生列出并命名课堂上出现的形状。如果可能的话，为他们提供操作性材料，这样对他们来说更加具体。由此研究的形状可以在视觉艺术项目中再现：代表空间宇宙。

我们可以为学生提供：

• 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.)
• 如果我们想在固体上工作，就可以在 3 维空间中进行生产，这将是操纵图案的机会。
