Day 12

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!

I also started filling in our class Word Wall today.  Will continue to add to the chalkboard as we progress through the year!Image
