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.

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

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