Here’s an addition to #NoticeWonder. #ElemMathChat

Let's learn how to factor quadratics where the leading coefficient isn't 1 without guessing and checking. (Okay I know that sounds boring but I like this video lol)

How to divide a number by 5. Double the number. Move the decimal place one unit to the left. You're welcome. 4283/5 8566 856.6 It's *magic* (and i'm sure it has nothing to do with the fact that 5=10/2 😜)

Natures strength or a parabola 🤔 #MathsToday ❄️

In #MathsToday I had all the students at the whiteboards and asked them to solve ax^2+bx+c=0 by completing the square. They were so surprised to get the quadratic formula as their answer, and then they were proud they had derived this mystical formula without even realizing they were doing it.

I did this fellowship under its slightly different name last summer. It was a great opportunity to hang with some dope people for a day and a half and to get plugged in with new resources/networks thereafter. Applications are open now! amplify.com/amplify-clas... cc #iTeachMath ♾️ 📣
