How to work figures 3D in the classroom?

To study the 3D figures in Primary Education there are many activities, but then I'm going to explain two different activities in which we can work figures 3D:

Activity 1:

We need to do this activity very simple material such as toothpicks and clay. Students will be joining the toothpicks with the clay, which will be the vertexes. An example of this we can see in the image below:

Depending on the age of the students, the teacher can do before an example for children to see how it is done.

Activity 2:

In this activity, children will need scissors and glue, and the tabs that teacher gives them. From these templates, students cut and can make, for example, a triangular pyramid.

This is a very simple activity in which students can learn how to create a figure 3D, in addition they will be able to see the faces that form the figure easer.

With this activity, student will learn how to create a lot of type 3D figure.
