In Ontario, in our new(ish) grade 9 course there are expectations around number systems and the cultural significance of numbers. This is relatively new for our classes to focus on and so sometimes resources are sparse. That being said, it's great when people lay out a whole lesson that fits it and gives an interesting perspective. Thanks to @MSBJaccobs
