Mrs Hassall’s maths group have been testing the theories of ratio from Leonardo Da Vinci’ s ‘Vitruvian Man’. Did you know that the distance from your hairline to the bottom of your chin x10 should be the same as your height? 24 times the width of your palm should also be the same length. If the distance from your elbow to the tip of your longest finger is a quarter of your height you are in perfect proportion! Our findings proved that even though we’re extremely good at measuring, we aren’t quite in perfect proportion – are you?
This week in Maths, Reception have been learning to share a number of objects equally. Yesterday the children were given a set of numbers to 20 to investigate if that number could be shared equally. The children were super investigators and found that some numbers such as 9 and 13 cannot be shared equally. We have also been learning to verbalise our sharing by saying, for example, “if I share 12 equally, they will have 6 each”. Fantastic work everybody! Click on the links in the picture below to hear the children verbalising their sharing.
As part of our shape and geometry lessons, Year 4 spent Tuesday’s lesson completing a range of reasoning activities. We have been looking at the different types of triangles, and how we can identify them by their different properties.
The children completed 4 activities. Firstly, there was a sorting activity using a home made Venn diagram! The children came up with their own criteria to sort the triangles, such as if they contained any right angles, or had sides all of different lengths. Then, the triangles were sorted and placed into the Venn diagram.
Next, there was a puzzle to solve as the children were given an image and asked to count how many triangles they could see. Many of the children found this harder than it first seemed, but they persevered and found that there was more than they thought!
The third activity involved using a clock face to draw different types of triangle. The children had to think about how to draw equilateral, scalene and isosceles triangles by drawing lines from the different numbers on the clock face.
The final challenge involved working with a partner. The children sat back to back – one partner had a shape in their hand that they had to describe to their partner. The partner had to try and draw the shape onto their whiteboard. It was great to hear all of the fantastic mathematical language from the children!
The children really enjoyed all of the activities and it was great to hear them talk about the different properties of the shapes. Fantastic work Year 4
In our final Maths, Fun And Games session we used our skills in division to re-scale a scone recipe. We weighed and measured ingredients, mixed and manipulated sticky dough and finally we enjoyed sharing what we had made.
Many thanks, once again, to all of the parents who took part in these sessions. Your support and participation has been awesome and inspiring.
