How can we visually show why something like sqrt(90)=3sqrt(10)? Rewriting square roots can be seen visually!
(I know the title doesn't sound appealing but I honestly really like the concept lol)
@ProfessorMarin@LieslMcconchie 100% agree. Also personal opinion I don’t even like using the word trick in math because it’s about understanding why the technique works. I think trick implies there’s magic going on behind the scenes.
8th graders spreading some math love around the school before Thanksgiving break! Very creative interpretations of proportional relationships! @SwampMiddle#iteachmath#mtbos
We expect more from the College Board. The proposed AP Precalculus is a misguided money grab with harmful impact on school mathematics. See our case in this open letter and, if so inclined, retweet and/or add your name as a math teacher for change: https://t.co/JHv6fialX2
Wanted to show off some of the amazing projects 8th grade math students have been working on as we wrap up our systems of equations unit. It’s so empowering to watch them make all these meaningful connections and I’m so proud of all their hard work! #iteachmath#everybodymaths
@Ms_Claveau@MathigonOrg I got so many ideas from @Desmos and @IllustrateMath. Their lessons are very thoughtfully created and propose ways for making their content accessible and within reach for all students.
@TimeFliesEdu I think this is a really good idea. Most of the time students just write +- when they take the square root of both sides but never really understand why they do it.
Today Algebra 2 ss worked backwards, using multiplication as a vehicle to solving division problems with polynomials. Ss embraced the productive struggle while discovering the relationship between division and factoring. We concluded with a generalization of factoring x^n-1!
@caitlyn_weston Benjamin Dickman states something along similar lines "By formulating problems, rather than routing exercises (Schoenfeld 1992), and ensuring that solving articulate their reasoning, we may design tasks of high academic and intellectual quality that allow for extended engagement"
