What is 2 apart?

"What is 2 apart?" means finding numbers that have exactly one number between them.

Imagine you're counting your toys on the floor. You pick up toy number 4, and then you count two more, 5, 6. Now, 4 and 6 are 2 apart because there's just one toy in between them, which is 5.

Like Steps on a Staircase

Think of the stairs in your house. If you're standing on step 3 and you take two steps forward, you’ll land on step 5. That means step 3 and step 5 are 2 apart, there's one step (step 4) between them.

A Simple Game

Try this: say the number 7, and then count two numbers after that, 8, 9. Now, 7 and 9 are 2 apart. Just like when you're playing with your blocks, and there's one block in between two others!

So, being 2 apart is just a fun way to say there’s exactly one number or step or toy in between them, not too close, not too far!
