Counting patterns – up to 100

key notes :

What are Counting Patterns?

Counting patterns are like secret codes in numbers! They help us understand how numbers are organized. When we count, sometimes we add the same number each time. This makes a pattern!

Counting by 2s

Let’s start with counting by 2s. We add 2 each time. Imagine you have pairs of socks. You have 2 socks, then you get another pair, so now you have 4, then 6, and so on.

Example:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

Imagine drawing circles in pairs to represent this pattern! 🔵🔵 🔵🔵 🔵🔵 …

Counting by 5s

Now, let’s try counting by 5s. We add 5 each time. Think about your fingers on one hand. You have 5 fingers. If you have two hands, you have 10 fingers, and so on!

Example:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50

Imagine drawing stars in groups of 5! ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ …

Counting by 10s

Counting by 10s is super easy! We add 10 each time. Think of having stacks of 10 blocks. If you have one stack, you have 10 blocks. Two stacks? 20 blocks!

Example:

10, 20, 30, 40, 50, 60, 70, 80, 90, 100

Imagine drawing towers of 10 blocks! 🧱🧱🧱🧱🧱🧱🧱🧱🧱🧱 🧱🧱🧱🧱🧱🧱🧱🧱🧱🧱 …

Spotting Patterns on a Number Line

A number line can really help to understand number patterns visually. Each jump on the number line is the same amount, according to the counting pattern (2s, 5s, 10s…)

Example:

Let’s visualise the ‘counting by 5s’ example as jumps on a number line.

Each jump represents adding 5. We can easily see the pattern developing.

Why are Patterns Important?

Understanding counting patterns helps us:

• Count faster
• Solve math problems more easily
• See how numbers are related
• Become math superstars! ⭐

Next Steps

Now that you’ve learned about counting patterns, practice counting by 2s, 5s, and 10s. Ask your teacher or parents for more examples and fun math games!
