GRADE: 7

CURRICULUM AREA(S): Mathematics, Language

- investigate, using concrete materials, the angles between the faces of a prism, and identify right prisms

- distinguish between and compare similar shapes and congruent shapes, using a variety of tools and strategies

**Mathematics: Measurement**

- determine, through investigation using a variety of tools and strategy, the relationship between the height, the area of the base, and the volume of right prisms with simple polygonal bases

**Language: Oral Communication**

- 2.1 identify a range of purposes for speaking and explain how the purpose and intended audience might influence the choice of speaking strategies

- 2.4 use appropriate words, phrases, and terminology from the full range of their vocabulary, including inclusive and non-discriminatory language, and a range of stylistic devices, to communicate their meaning accurately and engage the interest of their intended audience

- 2.7 use a variety of appropriate visual aids to support and enhance oral presentations

- Familiarity with the Rubik’s Cube, its functionality, and the goal of the puzzle
- Knowledge of what an algorithm is and how to create one. (Definition: An algorithm (pronounced AL-go-rith-um) is a procedure - a step-by-step set of operations - or formula for solving a problem)

These lessons provide opportunities for teachers and students to gather evidence of learning through teacher, peer, and self-assessments; and learning goals and success criteria. See *Growing Success: Assessment, Evaluation, and Reporting in Ontario Schools, Chapter 4* for more information.

- Rubik’s Cubes
- Computer Projection Device
- Internet

- Solve the Rubik’s Cube.
- There are many websites and YouTube videos on the algorithms that can solve the Rubik’s Cube puzzle.
- This is just one Rubik’s Cube Algorithm.
- Each step could take students or partners a variable length of time

**Math**

Number Talk about the relationship between the height, the area of the base, and the volume of the Rubik’s Cube.
Number Talk about translations, rotations, and reflections and congruent shapes.

**English**

Choose one algorithm or step in solving the Rubik’s Cube and create a brief instructional video or oral presentation to show someone how to be successful.

Not all steps in solving the cube need to be mastered.

Share the instructional videos or oral presentations.
