If you are having trouble with the May Puzzle of the Month, I have produced this interactive version to help you. There is also an opportunity to extend the puzzle and turn it into an investigation, so pull up a chair at the circular table and have a go. www.transum.org/Maths/Invest...

Today, 29th of January, is National Puzzle Day in the US. I have just counted and there are 428 free puzzles on the Transum puzzle page. The image below shows some examples. www.transum.org/Software/Puz... I hope you have a very Merry Puzzle Day and a Happy New Conundrum 🌞
