MATHS

Our maths this morning involved going outside to investigate trees! 

We looked at the vocabulary of circles: circumference, radius, diameter and applied our knowledge to measure and calculate not only the circumference of trees, but the approximate age of them using the calculation: circumference of tree divided by 2.5. An enjoyable lesson for all.

Volume

We worked out the volume of a variety of different cubes and cuboids by multiplying the length, height and depth.

We then got into pairs and put a barrier between us so that our partner couldn't see what we were doing.

We used between 15 and 25 cm cubes to make a single shape.

Once we had done this we gave instructions of how to make the shape using the words: total volume, length, breadth and height.

When our partner had been successful we swapped round.

The challenge this morning was to work out the volume of the Treehouse!

Would it be tricky? Yes, it would. That was because the children realised that, in real life, working out odd shapes is harder than if they'd had the shape on paper to measure. 

First of all, they split the Treehouse up into manageable shapes, then drew a plan of what it would look like on paper.

The next thing was to understand how to work out the volume using the given dimensions. V= LxBxH

Although it was hard, by persevering, the children succeeded using their fantastic, mathematical knowledge!

Today we were working out the volume of the paper briquettes we have been making in class. We then worked out which ones were the best value for money.
