Halves, wholes and houses13 May 2021
Form 1 have been exploring the concept of halves, and making houses.
This week we have been doing a lot of work on halving. It is always important to start with the physical and practical in Maths and therefore the children have cut different shapes into half and then stuck them back together again.
The children have coloured half of various shapes too and lots of thought had to go into colouring half of a cake with some slices missing. The children found it much easier when I talked about two people having a fair share of pizza. Suddenly they all realised how to share half and half!
We then moved on to halving actual numbers and again the practical side of this was tested by building towers of blocks and then halving them. They checked their results by measuring the tower halves side by side and if they matched they had got it right.
A lot of thinking was had when I asked them to build a tower of three and then halve it. Some realised the odd numbered towers could not be divided into half as one would always be left over. Sharing out different items between 2, 3 and then 5 proved to be tricky but possible. Without realising it the children have begun to understand the concept of division!
When I asked the children to fold an A4 sheet of paper into half and then half again and again and so on, they were quite surprised to find that it was not possible to keep doing this. In fact, I think the maximum times a sheet of any size paper can be folded is about seven times. Do try it at home with your child and see if you can do better.
I must thank you for all the cereal boxes which have been put to good use as you can see from our colourful display of Material Street. The children loved making their houses and choosing different materials for each roof. They are very proud indeed of their creations.
