 # Building with the Mind's Eye

## Curriculum Goal

#### Primary: Geometry and Spatial Sense

• Compose and decompose two-dimensional shapes and three-dimensional figures.
• Describe the relative locations of objects using positional language.

## Context

• This is a teacher-led activity that can be conducted with a whole class or small groups.
• Students and the teacher sit on the floor in a circle.

## Materials

• Coloured multilink cubes
• Building with the Mind’s Eye Slide Deck (Appendix A)

## Lesson

• Before the lesson, construct simple 3D figures using different coloured cubes and note how to build the figure step-by-step. Alternatively, use the images and script provided in the slideshow (Appendix A).
• Ask students to close their eyes.
• Describe how to build each figure step-by-step. A script is provided in the presenter notes of the slide deck.
• Ask students to visualize what the figure looks like in their mind.
• Present multiple unique figures made from coloured multilink cubes, only one of which is the actual figure that was described.
• Have students identify which figure they pictured and explain why the other figures do not match the given description.

## Look Fors

• Can children follow the instructions and select the correct figure described?
• Can children explain why the other figures are not correct?
• Do children use positional language to describe the relative location of each cube?
