#ALevelMaths - I’ve done both the further statistics and further mechanics AMSP course - they’re brilliant and I’ve got so much out of them. Grab a place before they go!

In #mathstoday I taught 1st lesson of AL stats. They used #Gapminder, #worldfactbook and the #OCR large dataset to produce graphs and plots in #Desmos. Also my #GCSEmaths resit students focused on nailing one mark questions in their 1st lesson.

Not sure if Pearson have added extra pure material to their mandatory pure, but the key non AS Maths topics needed for AS Further Maths are radians and double angle formulae. For Year 2 need to cover the advanced calculus, including DE, to be able to build on those skills in your FM lessons.

Here's a slight twist on an arithmetic grid for this week's #OCRMathsPuzzle. Find the values for p and q so that the arithmetic grid below can be completed. #MathsToday #UKMathsChat #RecreationalMath @cambridgeocr.bsky.social

210 has 16 factors.
Each factor can be placed in the 4 by 4 grid (one factor per cell), so that the sum of each row and the sum of each column equal the given expressions, where p and q are positive integers.

Find the values for p and q so that the grid can be completed.
Row 1: (4p + q)/(q - p)
Row 2: 13p + 9q
Row 3: 5 (p + q)
Row 4: p + 11q
Column 1: p + 2q
Column 2: 12p + 8q
Column 3: 10p +2q + 6
Column 4: 7p + 6q

Great session this afternoon. Always nice to hear positive feedback on the exams, but some points raised that I will be taking into meetings with the assessment and the product support teams. If you missed the webinar then email me at maths@ocr.org.uk to arrange a meeting to discuss the course.

$A rectangle is partially covered by a square, a regular hexagon and an equilateral triangle. The three shapes covering the rectangle just touch where their edges meet. One edge of the square, two opposite vertices of the regular hexagon and one vertex of the equilateral triangle just touch the edges of the rectangle. Work out the exact fraction of the rectangle that is covered by the 3 regular shapes.$

Having sat in sessions with representatives from all 3 exam boards I would say the feedback here is good advice for all A Level Maths students. Make explicit why your working does 'show that' Use concise, mathematical language and notation.

Here is today's #OCRMathsPuzzle to consider over half term. Two circles in a rectangle, measures shown in the diagram. What is the area of the rectangle not covered by the circles. #MathsToday #UKMathsChat #RecreationalMath #Area #Pythagoras #Circles @cambridgeocr.bsky.social

Two circles, with centres P and Q, are drawn on top of rectangle ABCD,
Each circle touches two sides of the rectangle, and the two circles touch each other.
The radius of circle P is 30 cm.
The radius of circle Q is 10 cm.
The length of side AD is 64 cm.

Work out the area of the rectangle that is not covered by the circles.

The graphs of two quadratic equations are drawn on the same axes.
y=x^2-10x+25 and y=3+6x-x^2
N and M are points on the curves, between the points of intersection. N is vertically above M. Which value of x gives the maximum distance between N and M?

Nice start, but not the answer I got. You look to have used the area formulae for a right angled triangle, but don't we have 8 isosceles triangles in the octagon?
