Last week we spent a little time revising some of the mathematical topics and concepts we’ve been learning in the classroom. However, we didn’t simply open up our books and start reading (I’m much too kind to do such a thing), instead I created a set of QR codes with maths problems on them and put them onto laminated A4 sheets. I also wrote clues for the students to follow (like a treasure hunt) and an extra code on each card. The extra codes were all a part of an order of operations problem so they had to be placed in the correct order for it to give the right answer. It all sounds tricky, but the students enjoyed it. The cards were placed around the school and the students, in groups, set off with their maths books (for reference) and an iPad (to scan the codes) to follow the clues and solve the problems. I’d have to admit that it was tricky to set up, but I’d also say it was worth it. Check out the photos.
