Matt originally made these as a gift to give to a few schools he works with. But word got around and he was inundated with requests to buy them. So here they are. Available to buy.
These stickers are themed like the school reward stickers of old, but with advanced high-school maths content. Perfect for telling students that their recent improvement is a good ∫cos(θ).dθ or that their work is Σ(awe).
Sold as ten sheets of twenty-four stickers each. And we'll sell them to anyone, teacher or otherwise. There is no legal restriction against buying reward stickers yourself and putting them on your own work in the office.
