📊 Detailed Explanation of Counting by Twos, Fives and Tens

Counting by twos, fives, and tens is a very useful skill in Year 2 Maths, which helps you count faster and understand numbers better. Let’s learn how to count by these numbers with simple steps and examples!

👣 Counting by Twos

When we count by twos, we start at 0 and keep adding 2 each time. It’s like jumping two numbers forward every time we say a number.

For example, start at 0:

0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

You count every second number, which means you are counting pairs. This helps when you want to count things in pairs, like shoes or socks!

✨ How to practice

  • Use your fingers and count pairs (two fingers at a time).
  • Jump on a number line, stepping two numbers forward each time.
  • Count pairs of objects around you, like pairs of pencils.

🖐️ Counting by Fives

Counting by fives means you start at zero and add 5 each time. It’s like jumping five numbers ahead every step.

For example:

0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50

You often use this to count groups of 5, like a hand with 5 fingers.

✨ How to practice

  • Count your fingers in groups of five.
  • Use a number chart and highlight every 5th number.
  • Count coins that are worth 5p to see how this works in real life.

🔟 Counting by Tens

When we count by tens, we add 10 each time. This is a bigger jump, like counting by whole sets of ten!

For example:

0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

This helps when counting lots of things quickly or reading clocks by tens.

✨ How to practice

  • Use a number line to jump up by 10 each time.
  • Look at a clock and count the minutes by tens.
  • Count groups of 10 objects like ten pencils or ten blocks.

🚀 Tips for Counting Fast

  • Use fingers or objects to group numbers in twos, fives, or tens.
  • Practice with a number line or number chart to see the jumps clearly.
  • Say the numbers out loud while counting to remember the pattern.

By practising counting by twos, fives and tens every day, you’ll become faster and better at Maths! Keep trying, and you will soon count with confidence! 🎉
