Bricks and Tiles
This activity from Cre8ate maths investigates the lines of horizontal and vertical weakness in walls. Initially students are shown four walls and have to identify the lines of weakness in them, before finding the smallest rectangular solution which has no lines of weakness. Students should record their designs as they work and use them to improve upon. Dominoes could be used for this task as they are in the same ratio as a brick.
Drawing tiles demonstrates how a design can be tessellated to create patterns and students could create a tile using the draw toolbar within Microsoft Word, as this will allow them to experiment with rotation and reflection possibilities very easily.
Square tiles gives rich opportunities to consider reflective and rotational symmetry and could be used to introduce art from different cultures. Guide lines for a square tile are provided, with lines of symmetry marked, to support students when completing this task.
