This was fun on two levels. First of all, it's an escape room, so fun. But on another level, the amount of cool @Desmos programming that @SweenWSweens must have had to pull off was unreal. Give it a shot. There may or may not be hints in the comments.

You should definitely check out PlayWithYourMath.com for some fun ways to mix play and math and this task is also quite appropriate for the thinking classroom. Especially if you want to focus on looking for patterns and connecting to algebra.

Although I think this could be a divisive issue, I don't think it's a real issue. That is, there are people that look at a question like this and say students must solve by some algebraic method. But in the way it's asked, there is no indication that a particular method is required. And so if a student were to use graphing (which is completely legitimate) or even substitution of values (also completely legitimate) they should be given full credit. Luckily, here in Ontario, we can take care of this by just asking the question in the right way. Since we have the four assessment categories, if we ask this question in this way, then it is an application question since students can choose the method that they want to use to answer. If you want to make sure they use algebraic methods then you could just tweak how you ask the question and add bit to the front end of the question "Use an algebraic method to show which polynomial is equivalent...." and now it's a knowledge question

This week is the first half of the OAME 2022 virtual conference and so I thought I would feature some of the sessions of note. One of our Featured sessions was from Dr. Andrew Allen and titled "Exploring the Relationship between Mathematical Knowledge and Political Knowledge through Critical Mathematical Literacy" and by all accounts it was a great session. You can check out the slide deck here and even if you don't hear him go through them, there are enough resources embedded in them that you will be satisfied.
