# Square Moves

## Curriculum Goal

#### Primary: Geometry and Spatial Sense

• Give and follow multistep instructions involving movement from one location to another, including distances, half- and quarter-turns.

## Context

• In person, students should have a clear view of the Challenge.
• Online, the teacher will share their screen in a virtual space; students will use Jamboard.

## Materials

• Google Slide Deck with challenges and teacher prompts in presenter notes (Appendix A)
• In-class version: 10 square tiles per student (same colour)
• If possible, use magnetic tiles with a metal cookie sheet. This will be easier for students.
• Online version: Jamboard with the different challenges (Appendix B).

## Lesson

• Inform students they will be playing a game that will challenge them to transform one shape into another by moving square tiles.
• Show Image 1A to the class and invite students to recreate it.
• If using Jamboard, students will see Image 1A already constructed.
• When everyone is ready, share Image 1B, alongside the Image 1A.
• Ask students to imagine how they could make the new shape by moving only one square on the original image.
• Before students make any moves on their own, invite students to use positional language to describe how they would make the transformation.
• Repeat with Image 2A and 2B, etc. As the challenge increases, so too does the number of moves required to complete the challenge.
• Have students find the minimum number of moves to transform Shape A to Shape B each time.

## Look Fors

• Are students visualizing the moves in their mind? Are they gesturing while visualizing?
• What kind of positional language are students using?
