Second class have had great fun learning all about metres and centimetres. First of all we had to measure with our fingertips. We discovered that the width of our finger is about a centimetre. Then we used our span, which is when you hold your arms out as far as possible. This is about a metre.
Then we got measuring lots of things. We had to do lots of estimating (good guessing) first.
Did you know that our classroom door is almost a metre wide and just over two metres high!
