Three number ideas

Numbers go in order: 11, 12, 13, … all the way to 20.
Each number is one more than the one before it.
Counting up makes numbers bigger; counting back makes them smaller.

Let us try. Put these in order: 15, 12, 18, 13.

Smallest to biggest: 12, 13, 15, 18.

The number before is one less; the number after is one more.
Before 14 is 13; after 14 is 15.
A number between two others sits in the middle — 12 is between 11 and 13.

Skip counting jumps in equal steps: by 2 (2, 4, 6, …) or by 5 (5, 10, 15, …).
A number pattern follows a rule, like "add 2 each time".
Once you spot the rule, you can say what comes next!

Remember: "before" means one less, "after" means one more. It is easy to mix these up — say the count out loud to check.
