Learning Objectives
- Understand how shapes fit together to make patterns
- Learn about floor patterns and tiling
- Explore symmetry in brick patterns
- Recognize how different arrangements of the same shape create different designs
Key Concepts
Patterns with Bricks
Bricks are rectangular blocks used to build walls and floors. Bricklayers arrange bricks in different patterns. When bricks are placed in the same direction, they make one pattern. When some are placed lengthwise and some widthwise, a different pattern appears. The same bricks can make many different designs depending on how they are arranged.
Tiling and Covering
Tiling means covering a flat surface using shapes without leaving any gaps or overlaps. Floor tiles are a good example of tiling. Squares, rectangles, and triangles can tile a floor perfectly. Circles cannot tile a floor because they leave gaps between them. Look at the floor in your house to see what tile pattern is used!
Counting Bricks
To count the number of bricks in a wall, you can count the rows and the number of bricks in each row, then multiply. If a wall has 5 rows and each row has 10 bricks, the total number of bricks is 5 x 10 = 50 bricks. This uses multiplication, which is faster than counting one by one.
Making Designs
You can create beautiful floor designs by colouring tiles in a pattern. For example, colour every other tile red and white to make a checkerboard pattern. You can also use L-shaped, T-shaped, or zigzag patterns. Architects and designers use these ideas to make beautiful buildings and floors.
Important Terms
