Estimating and Measuring

In Maths, Room 3 are learning to make sensible estimates and measure accurately. We started off by estimating and measuring objects around the room using our hand spans. We worked out that not all our hand spans are the same size, so our answers were not all the same.

We have learnt the meaning of words .... 'length' and 'width'. The length of a rectangle is the LONG side, and the width is the SHORT side.

Then we learnt to estimate and measure objects/distances in cm and metres. We have learnt that Perimeter means distance around the edge, and Area means the space inside a shape. We have been learning to calculate perimeter and area of square and rectangles.

We are now starting to learn about measuring volume (or capacity). We are learning to measure water using millilitres (ml) and litres (l).

Stay tuned for more photos ...

Can you work out what the PERIMETER would be of a rectangle that had a length of 5cm and a width of 2cm?

Do you know what the AREA would be?
