The patterning that students have been working on in their primary years leads to algebraic thinking as students move into higher grades. The Big Ideas that students will be working on are:

1. There is always an element of repetition in a pattern, whether the same item repeats or there is a consistent change in the pattern.

2. There are different ways of representing patterns.

3. Many other mathematical concepts can be simplified by using patterns.

4. Algebra is a way to represent and explain mathematical relationships.

## Unit 3

We will be learning how to extend, describe and create repeating, growing and shrinking number patterns. We will also be creating number patterns involving addition, subtraction or multiplication.

We will also be introduced to making predictions about a future term in a pattern based on how the pattern grows or repeats.

Typical problems could include:

"Explain the pattern rule in the following pattern 1, 2, 4, 6, 7, 9…"

"Create a pattern block train by alternating one green triangle with one red trapezoid. Predict which block will be in the 30th place."

Take the opportunity to practice these problems, and problems similar to these with your child at home. As much as possible, try to embed your math practice into your daily activities with your child. An excellent tool for creating and working with pattern blocks, is the Pattern Block template found at the National Library of Virtual Manipulatives.
