## AB patterns

We can represent repeating patterns using letters.

If a pattern core has two terms that repeat repeatedly, we call it an AB pattern.

A represents one of the terms and B represents the other.

This pattern is an AB colour pattern of two red hearts, three yellow stars, two red hearts, three yellow stars, two red hearts, and three yellow stars.

There are many ways to describe a shape. When we describe the appearance of a shape or object, we are describing its attributes. One attribute could be the number of sides a shape has.

The pattern is:

• light blue triangle, dark blue square, light blue hexagon, dark blue triangle, light blue square, dark blue hexagon…

This AB pattern is: Light blue, dark blue, light blue, dark blue…

After exploring the pattern, reflect on the following questions:

• How many sides do each of these shapes have?
• What do you notice about each shape in the pattern?
• What is the pattern core based on the number of sides?

Record your ideas in a notebook or a method of your choice.
