Today in Gr8 #tvdsbFRL, we are folding triangles to see how the angles of ea. vertex add to 180deg. We are using @73tracygrace’s angle estimator to estimate and then measure angle w/ protractor. We also compare w/orig to see formula relationship =(bxh) then =1/2(bxh) and ext.ang.



















Ss @Westmount_ps use doubling and halving to simplify division and multiplication scenarios in Mrs. Shantz's class. "If I know my 2 facts, I know my 4 facts, and so I know my 8 facts" @73tracywhite, this is your classic case of double, and double double! ☕☺
