This item has no instructions

Constructing 3D Figures Using Cubes
Cuboid: a three-dimensional figure formed by folding a net of six squares.

#### Slide 6 -Slide

This item has no instructions

Analyzing Properties of Combined 3D Figures
Vertices: points where two or more edges meet in a 3D figure. Edges: straight lines where two faces of a 3D figure meet. Faces: flat surfaces that make up the boundaries of a 3D figure.

Write down 3 things you learned in this lesson.

#### Slide 9 -Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

#### Slide 10 -Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

#### Slide 11 -Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
