Kendall Posted September 20, 2019 Share Posted September 20, 2019 (edited) Convince me of the value of doing more than a few problems (or any) of solving 2nd order and higher order systems of equations by hand using augmented matrices. I don't want to be lazy about it, but I also don't want to do it just because it was taught for years. We are using the Foerster Algebra and Trig text for Algebra 2 Thanks, Kendall Edited September 20, 2019 by Kendall Quote Link to comment Share on other sites More sharing options...
EKS Posted September 20, 2019 Share Posted September 20, 2019 One reason might be so that you're grateful when you're finally allowed to use other means in college (this would be my son). 3 Quote Link to comment Share on other sites More sharing options...
Kendall Posted September 20, 2019 Author Share Posted September 20, 2019 https://forums.welltrainedmind.com/topic/658850-should-i-teach-augmented-matrices-in-algebra-2/ I knew I had asked this before! I tried to search on WTM for it in my activity, but it didn't show up. I just did a google search for this topic and one result was the thread I started above:)!
