Introduction
Hello, young mathematicians! Today, we’re going to learn how to count forward and backward up to 20. This will help us with all kinds of fun activities, like playing games and solving puzzles. Are you ready to start counting?
Counting Forward
When we count forward, we start with a number and say the next number. For example, if we start at 1, we count forward like this:
1, 2, 3, 4, 5…
Key Rules for Counting Forward:
- Start with a number.
- Say the next number by adding 1.
- Keep going until you reach 20!
Example:
If I say “3”, what comes next? Yes! It’s “4”! And after that, we say “5”.
Counting Backward
Now, let’s learn to count backward. When we count backward, we start with a number and say the number before it. For example, if we start at 5, we count backward like this:
5, 4, 3, 2, 1…
Key Rules for Counting Backward:
- Start with a number.
- Say the previous number by taking away 1.
- Keep going until you reach 1!
Example:
If I say “7”, what comes before it? That’s right! It’s “6”! And before that is “5”.
Tips and Tricks
- Use Fingers: You can use your fingers to help you count! Count forward by raising your fingers, and count backward by putting them down.
- Counting Songs: Sing counting songs! There are many fun songs that help with counting forward and backward.
- Visual Aids: Draw a number line! This can help you see the numbers and understand how to count up and down.
