Wednesday! Almost there. We began the basics of solving equations today…proving an equation to be true or false, given the value of a variable. For example, is 7 a solution for x + 3 = 10? Ha Ha so easy, they say! I admit, the examples we started with were pretty easy, but I stressed the importance of actually PROVING it. We did about 10 examples together and I made sure each student showed each step of plugging in the value of the variable, simplifying, then proving with an = or (not)= sign. How fun! And they really did a great job of showing these simple steps.
Tomorrow when we start actually SOLVING equations, this “proving” whether a value of a variable works for an equation will all make sense!
