The teaching community on twitter has been a daily source of inspiration for me over the years. I follow a variety of educators and # but I particularly enjoy and use ideas from the maths teachers I follow. This image is courtesy of @the_chalkface, a high school maths teacher in the UK but that doesn't put me … Continue reading Multiplication Grid Makeover
Last Counter Game
I try to create a playful atmosphere in my maths classroom but I'm not a big fan of maths games. I find the students are too caught up in winning to notice the maths.
