The lesson

You already know how to add and take away. Now it is time to get fast. When you see 2 + 3, just say 5. You do not need to count each time.

Tap each star and count out loud.
2 stars and 3 stars make 5 stars. See it fast, do not count one by one.
Try it together

Leo sees 4 apples and takes away 1. He knows right away it is 3. He does not count on his fingers.

Good to know

Practice the same facts again and again. Soon your brain remembers them fast, like your name. Say them out loud or play a quick game!

Fast facts within 5 come from practice, not counting every time.
