We began today by reviewing the homework from last night. Aiden did an excellent job on it. Next we moved onto the next section, on Simplifying Expressions. We have already discussed this concept of combining like terms. However, today we worked with fractions and decimals. We discussed how using the commutative property helps us arrange terms together that are alike. Then we used the order of operations to combine terms that are alike. We worked with expressions like: -3+1/3x-4.5+1/5x. I showed Aiden how to keep his work organized, and to do any scratch work on the side. That way he can keep his "messier" work away from the work that shows his steps on going from one line to the next. On the side, he worked out 1/3+1/5 so he could combine the x terms. He recalled how to add fractions by getting common denominators. After he simplified, to check his work, he let x=2. He substituted it into the original expression AND into his simplified expression and verified that they were in fact equal.
