Hello! Today we are going to count all the way to 100. We will also learn to count in 2s and 5s. Get ready to count out loud!
Counting forward to 100
When we count forward, each number is one more than the number before it.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 …
After 10 comes 11, 12, 13 … all the way up to 100. A hundred chart helps us. Each row has 10 numbers. The numbers in a row go up by one. The numbers in a column go up by ten.
You can start counting from any number. Try starting at 37: 37, 38, 39, 40, 41.
Counting backward
When we count backward, each number is one less. It is like a rocket getting ready to blast off!
10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 – blast off! 🚀
Try counting back from 64: 64, 63, 62, 61, 60, 59.
Counting in 2s and 5s
Skip counting is a quick way to count. We jump over some numbers.
- In 2s from 0: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
- In 2s from 1: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
- In 5s from 0: 0, 5, 10, 15, 20
Count your shoes in 2s. Count your fingers in 5s. Two hands make 10 fingers!

Maths words
Say these words with a grown-up. Can you use each one in a sentence?
count forward · count backward · one more · one less · hundred · skip count · next
Try it at home
- Count the steps as you walk up the stairs. Count back as you walk down.
- Count pairs of socks in 2s.
- Do a “rocket count” from 20 back to 0. Jump up at zero!
- Say the numbers from 50 to 100 while a grown-up points to them on a calendar or a chart.
For parents and teachers
After this lesson, your child should be able to:
- count forwards and backwards in ones from any number up to 100
- use a hundred chart to find the next and the previous number
- count in 2s (from 0 and from 1) and in 5s (from 0) up to 20 and back
Tip: start counting from different numbers (e.g. 47, not always 1). The jump from 29 to 30 or from 69 to 70 is often the tricky part.
