Watch: What is a number line?
A number line can be used to add and subtract.
Watch the video to learn what a number line is, and how to use it!
A number line is a great way to add and subtract. Let's see how our meerkat uses the number line.
First up, we'll try adding.
Let's start with 6 plus 3.
Largest number first, that way you do less counting.
Then we count 3鈥1, 2, 3鈥nd we land on 9.
So 9 is the answer.
If we want to subtract, you count down the number line.
To work out 5 minus 3, we start at 5 and count down 3鈥1, 2, 3鈥ur answer here is 2.
You can always rely on a number line to get you out of a hole.
