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. I think that comes down more to the way I structure the lesson rather than the value of the game itself. … Continue reading Last Counter Game

The first kept the inquiry focused on area - the second left the inquiry far more open but eventually came … Continue reading Area Prompt
Division prompt
Questions and comments: I think 42 x 14 is the same as 84 x 7 because if you split 84 you get 42 and if you split 14 you get 7. Why does it say that 42 x 14 = 84 when the answer is really 588? I think the answer to 42 x 14 … Continue reading Division prompt
