Learning Goal

Students will be able to:

1. Predict the next number in the number pattern.
2. To be able to see patterns between the numbers.

60

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
