This semester I am redeveloping Mathematics for Primary Educators, the (ideally) first maths content course for our pre-service teachers who choose to specialise in maths. I have a notebook full of 'things I want to do right' this time, but it mostly boils down to giving students many opportunities to have mathematical conversations, and for … Continue reading Three looks at a WODB for numbers

#QuarterTheCross Card Sort
It is no secret that Quarter the Cross is one of my favourite tasks. I've written about it twice before: as a Day 1 activity and in connection with Fraction Talks.
