A PuzzleTime favourite from last week: Add the fewest number of toothpicks so that Willie only has one way to lie down.
Ben Sparks and Brady Haran team up to solve a delicious puzzle.
Mathologer highlights some beautiful mathematics.
Simon Anthony solves a highly symmetric sudoku with some special rules.
Teaching is an experimental science.
One of the best features of your puzzles is how they engage a wide spectrum of learners, something that is difficult for teachers. Your math puzzles are remarkable and children enjoy and learn from them regardless of their mathematical understanding. This is as close to a “silver bullet” as I’ve seen.
It is impossible to be a great math teacher without teaching great mathematics.
In elementary school a quality math education has these objectives in order of importance:
James Tanton and the Global Math Project has created an exceptional framework for teaching bases that is essential in every elementary school classroom. It’s called exploding dots.
The Julia Robinson Mathematics Festival and its founder Nancy Blachman refine the pedagogy of problems and promote a non-competitive alternative to competitions. They have a strong commitment to the Spanish community.
Brady Haran’s Numberphile is one of the top math channels. Most of the videos are not appropriate for the elementary school classroom, but there are many exceptions like this video on the dollar game by Dr. Holly Krieger.
Mathologer produces beautiful videos for his youtube channel. Most target middle and high school students, but this video deserves watching by elementary school teachers as well.
Grant Sanderson’s phenomenal videos on his 3blue1brown youtube channel are stunningly beautiful. They are best for high school and beyond.
