- 3Identify the missing number in a counting sequence
Mini Lesson
Numbers can go all the way to 1,000 — and you can get there by taking big jumps of 10 or 100!
Count forward by 10s
- Add 10 each time: the ones digit stays the same and the tens digit goes up by 1.
- Example: 120, 130, 140, 150…
- After 190 comes 200, then 210, 220, 230…
Count backward by 10s
- Subtract 10 each time — reverse the same pattern you use going forward.
- Example: 350, 340, 330, 320…
Count by 100s
- Add or subtract 100 each time: only the hundreds digit changes.
- Forward: 100, 200, 300… all the way to 1,000.
- Backward: 900, 800, 700… all the way down to 100.
Words to know
Count forward
To say or write numbers in order from smaller to larger
e.g. I counted forward by tens from 100 to 200.
Count backward
To say or write numbers in order from larger to smaller
e.g. I counted backward from 50 to 0 by tens.
Sequence
A list of numbers that follow a pattern
e.g. 120, 130, 140 is a sequence that adds 10 each time.
Tens
Groups of ten ones
e.g. Counting by tens means jumping 10 each step.
Hundreds
Groups of one hundred
e.g. Counting by hundreds: 100, 200, 300, and so on.
Missing number
The number left out of a sequence that you must find
e.g. In 70, ___, 90 the missing number is 80.
Ask yourself: "Am I counting forward or backward? Am I jumping by 10 or by 100?"

Tip: When you write 340, the digit 3 means 3 hundreds and the digit 4 means 4 tens!
