Similarity and Proportions

We looked at similar triangles today in grade 9 as a way to practice ratios and scale factors. We did a few examples, and made a pseudocode to calculate the proportionality constant between the similar triangles, and then students had some questions to solve in groups up at the walls.

We’re trying to work in some pseudocode as we go this year so it’s not a shock when we look at EQAO preparation.

It has been helpful because students can look at the algorithm in code and then use it to help them with the process.

We’re getting better at expressing our steps and solving equations with proportions.
