Ruler time

Today for maths we acted like Scientists and had to write down as many things as we could about rulers. We had to work as a team to look very closely at the ruler. Here are a few things we noticed:

Rulers are 30 centimetres or 300 millimetres long.

The gaps between the numbers are exactly the same. 

We start measuring from the 0. 

There are 8 little lines and 1 big line between each number.

Together as a class we discussed why these thugs are important.
