# Number Patterns

## Overview

In math, there are lots of possible **number patterns**! **Patterns** are helpful in figuring out missing numbers or predicting the next number in a sequence.

**Here are some examples:**

Let’s take a look at one of those number patterns more closely.

**This one is counting by twos:**

2, 4, 6, 8, 10

We can begin a pattern with any number, too! Let’s say, the number pattern is still counting by twos, but we start with the number 10:

10, 12, 14, 16, 181

What if we started with an odd number and counted by twos? That number pattern would look like this:

3, 5, 7, 9, 11

To discover the pattern, we have to look at the difference between one number and the next one after it. Take a look at this pattern:

5, 10, 15, 20, 25

The difference between 5 and 10 is 5. And the difference between 10 and 15 is 5. And the difference between 15 and 20 is 5. **Do you see a pattern?** That’s right! It’s adding on 5 each time.

In math, there are also number patterns using **shapes**. When you spot the pattern, you can fill in the **missing** shape or **predict** the next shape. Check out the patterns below:

There are so many different patterns that can be made with shapes!

**Let’s take a closer look at this pattern of mugs:**

Starting at the beginning, you can see there’s one red cup, then two blue cups, then one red cup, then two blue cups, and so on. This creates a pattern!

Let’s look at one more shape pattern. This one is with cups:

Starting at the beginning, the pattern is one blue cup, one green cup, and one yellow cup repeating over and over.
