Mini Lesson
Numbers go all the way to 100 — and you can count every single one of them!
Counting by ones
- Start at any number and say the next number: 1, 2, 3 … all the way to 100.
- Example: Start at 7: 7, 8, 9, 10, 11…
- Each number is exactly one more than the number before it.
The hundred chart
- A hundred chart has 10 rows and 10 columns — 100 squares total.
- Each row starts at a new ten: 1, 11, 21, 31 … 91.
- Moving right adds 1. Moving down adds 10.
Counting in groups of ten
- 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 — these are called decade numbers.
- Every decade number ends in a zero.
The last number you say tells how many
- When counting objects, the last number you say is the total count.
- Count each object once — never skip, never count twice.
Words to know
Hundred chart
A grid with 10 rows and 10 columns showing the numbers 1 to 100
e.g. I found 47 on the hundred chart.
Decade number
A number that ends in zero, like 10, 20, or 30
e.g. 40 is a decade number.
Count forward
Saying numbers in order, each one bigger than the last
e.g. I count forward: 5, 6, 7, 8.
Total
How many objects there are altogether
e.g. The total of my apples is 8.
Ask yourself: "What number comes after 29? After 59? After 99?"
