Lesson Topic
4.2 Generating Equivalent Expressions
Lesson Outline
We started the day by reviewing the assignment that Aiden had with a substitute on Friday. He got a 100%! I made a few comments to him regarding his notation. He needs to get into the habit of instead of writing 4xp for "four times p" to just writing 4p instead. That will come with more practice. The lesson today was on equivalent expressions. In a word problem we discussed if we spend $300 on supplies for a concert and sold tickets at $6 each, how could we write an expression to represent the profit made from the concert ticket sales. Aiden easily came up with the expression 6t-300. Then we considered -300+6t and I asked Aiden if it was the same. He agreed it looks different, but essentially it's equivalent. We then considered 6(t-50). At first Aiden dismissed it (where'd the 50 come from?), but then I reminded him of the distributive property. He applied the 6 to the parenthesis and realized that it would also give us 6t-300. We considered if t=100 tickets sold, then each of the given expressions would result in a $300 profit. The purpose of this is to recognize that we can generate equivalent algebraic expressions. Some of them are more ideal to use (like 6t-300 over the others), but as long as we do the order of operations appropriately, we can still yield the same results.
