Next, we put this into practice with a couple of examples which allowed students to get a refresher on how to solve for a missing side length.
Part way through those examples I lost half of my class to Inside Ride. The timing wasn't too bad as there an investigation up next. I "stole" this from myself - I made it for my grade 10 applied class. I think it is a nice combination of looking at relationships (linear & quadratic) and similar triangles. They got a lot of the first page done (perimeter) so will continue with area tomorrow.
Here is today's homework.
