Math Links for Week Ending May 13th, 2022

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

OAME 2022 - My talk this year at OAME was about introducing solving equations with a bunch of resources (Splat!, SolvmeMobiles and much more) including an update to my equation strips activities to now include physical and @desmos card sorts.

OAME 2022 - I was the tech host for a couple of sessions from @fredouellet0 on Clothesline Math and using @Desmos and even though they were in French, there was a lot of info to be had and resources that you could adapt to english. Check them out here:

OAME 2022 - @StandupMaths was one of our Keynotes at #OAME2022 and he reminded me of this great sets of data to show that you have to look at the data and not just the five number summary. All of these data sets have the same mean, standard deviation,  correlation and more.

I like focussing on the area representations of Pythagorean Theorem. And I like it even more when people build resources to help me do that

I'm a sucker for these fractal animations that seem to go on for ever.

These sorts of comparisons are always good for a rich discussion on percents

Do you have kids working with Square Roots? Have them try to prove this is true
