What comes next: breakfast, lunch, dinner, breakfast, lunch, dinner, breakfast . . . ? Before you get too hungry, follow this fun lesson and learn about patterns! And don't skip ahead to making your own music video!


Those 3 meals repeat each day, and because they repeat, we call that a pattern. Since patterns are predictable, we know what is coming next.

Even our stomachs know the pattern for eating! If you woke up in the morning and had a big steak dinner for breakfast, your belly would probably be upset because it is not used to that kind of food at that time of day.

We know that when you find a pattern, you can look at the parts to find the pattern unit or core and see how to make that pattern longer. Using 2 objects, there are AB, AAB, BBA, and AABB patterns.

In this lesson, you will learn how to extend those patterns to make them longer. Watch LeapFrog Learn & Grow Videos: Extending Patterns (below) for more explanation on extending patterns:

In the pattern below, find the pattern unit and then extend the pattern, or say what will come next:

cat-mouse pattern


The pattern unit is AAB, because it goes cat, cat, mouse. To extend the pattern, you would put a cat in the next box.

Let’s look at this pattern:

apple pattern

Say the pattern out loud: big apple, big apple, small apple, small apple, big apple, big apple, small apple, small apple.

  • What are the individual pieces of this pattern?


  • What part of the pattern is repeated?

Big apple, big apple, small apple, small apple!

  • What kind of pattern is it?


  • Now, if you were going to extend, or make the pattern longer, what are size are the next two apples?

If you said “Big” you are correct! How did you know?
