Right and Wrong
Sarah and Jack

Hi, Sarah! You seem in a good mood today.

Hi! Yes, I played volley-ball! It was great! Where have you been?

I’ve had a nice walk in the woods. You should see me climbing trees. Look at this nice straight branch I found! It must be 30 cm long.

No, it’s not! It’s about 40 cm long.

No way! It’s 30 cm.

I have a ruler at home. Let’s measure it and you will see that I am right!

It’s 25 cm long. We were both wrong.

Fortunately, we have a ruler that gives us the right answer!
