During class today, PJ and I discussed the introduciton of algebraic expressions. We discussed what a variable is and what a constant is. I showed PJ how in higher mathematics, instead of writing 3xt for "three times t" we just write 3t instead. We worked on translating math words into expressions. We learned sum=add, product=multiply, quotient=divide, difference=subtract. PJ practiced reading sentences and then rewriting them as algebraic expressions. He did great with this lesson!
