A row of apple, apple, banana fruit is named aloud until the pattern starts again, which shows that the core is apple, apple, banana; its 3 fruit are counted, and frames round every copy check that the core repeats all the way along. Two more rows show other cores, apple, banana and apple, banana, pear, before a one-line recap: the core is the shortest part that repeats.

Transcript

What the lesson says

Look at this fruit pattern. What part repeats?

The shortest part that repeats is called the core.

Say it with me: apple, apple, banana, apple, apple, banana, apple, apple, banana.

Apple, apple, banana. Then it starts again!

So the core is apple, apple, banana.

One, two, three. The core has three fruit.

Let's check: apple, apple, banana, apple, apple, banana.

Yes! The core repeats all the way along.

Cores can be different. This core is apple, banana.

And this core is apple, banana, pear.

The core is the shortest part that repeats.
