Here's our #OCRMathsPuzzle to end this week. 🙂

The vertices of a square just touch four edges of a regular octagon, as below.
The area of the square is 32 cm^2.

Work out the area of the regular octagon.

or 1 x (987 + 3 + 4 + 6) / (2 x 5) but still using brackets 🥲

Steve Walker @stevemaths.bsky.social · 6d

Thought I had a nice solution

2x(3x5+7+8+1+9+4+6)=100
but brackets not allowed 🥲

Here's this week's edition of #OCRMathsPuzzle! 😀

Work out the ratio of the area of circle M : the area of circle C in the form 1: n, giving n as an exact value.

Have a great weekend!

#UKMathsChat #MathsToday #MathSky #resources #puzzle

Two circles are drawn, with centres C and M and their circumferences just touching.

Equilateral triangle ABC is drawn over the circles, where M is the midpoint of AB and A and B are points on circles M's circumference.

Work out the ratio of the area of Circle M : the area of circle C in the form 1:n, giving n as an exact value.

Here's the #OCRMathsPuzzle for this weekend. 😀

Place nine different values that have a range (largest – smallest) of 8 into the grid below, so that the sum of each row, the sum of each column and the sum of each diagonal are all 26.

I thought the controversy was over using Venn Diagrams in this way - with repeated prime factors used as different elements.
My preference was always Trees simply because it seems easier in this format for students to check their own work. The structure is the working and short cuts are possible.

Image showing the Factor tree of 60 solved in two different ways. Method one using systematic approach, starting with 2 and then progressing through increasing prime numbers as appropriate. Solution 60 = 2 x 2 x 3 x 5.
Method 2 using number bond knowledge and recall of previous work, so 60 = 5 x 12 and remembering that 12 decomposes to 2 x 2 x 3. Solution 60 = 5 x 2 x 2 x 3.

The perimeter is exactly 38 cm so the sides must be rational.
