Todays puzzles are inspired by the wonderful puzzle book
Without Words by Australian maths guru James Tanton. I had to adapt them since Without Words has, predictably, no words in it. Part of the puzzle is working out what the puzzle is.
James is a co-founder of
The Global Math Project, a program that plans to thrill one million students, teachers, and enthusiasts with an engaging piece of mathematics during a week in October 2017. The goal is to share the marvel of mathematics with the world by simply decluttering mathematical content and revealing its inherent human connection, story, and natural uplifting joy, he says. Check it out.
Ill be back later today with the solutions.
I post a puzzle here on a Monday every two weeks.
Im the author of three popular maths books including Alexs Adventures in Numberland and the maths colouring book Snowflake Seashell Star.
