Shout-Outs for Penn State Penn State beat Penn on the Unit Test by 5 percentage points!!! Outstanding Performers: Miss Fabulous scores the highest in either section with a 99! Miss Awesome scores the second highest with 95 We had an average 11% improvement in test scores in all eleven skill areas from our first test on 9/19 Congratulations!

Shout-Outs for Penn Outstanding Performers: Ryan and Faith score a 94 Max F, Max T, and Ethan Score in the high 80s Tomorrow I will wear that loathsome and wretched red sox hat. Congratulations!

Food for Thought From one student survey in the Penn Class: Question: What would you like to see less of? Answer: I would like to see less goofing around so we can have more time to work. Congratulations!

More Food for Thought Penn outscored Penn State by 5% on our first quizzes. On this test it was 5.5% under Penn State Penn State’s scores went up 11% from the 9/19 test to the Unit Test Penn’s scores WENT DOWN 3.5%.... Penn State scored above an 80 in 7 of 11 skill areas. Penn scored an 80 in only 2 of 11 areas.. Congratulations!

Objective & EU OBJECTIVE: SWBAT solve two step equations by using inverse operations to isolate the variable. Essential Understanding: We do two-step equations the same way we do one step: identify the operation, use the inverse operations to isolate it. Copy all items in red in your notes WHEN FINISHED SIT IN ACADEMIC POSTURE!

Thinking Question How does math fit into the career you intend to have after college? Silently think about the answer & jot down your ideas Timer WHEN FINISHED SIT IN ACADEMIC POSTURE!

Two Step Equations -Two step equations are those which have two operations in them -We solve them the same way: identify the operation, do the reverse -ALWAYS do addition and subtraction before multiplication/division. Reverse PEMDAS…It’s much easier. The only exception would be if you have to distribute first (we’ll see this later) Work Silently & Independently; silent hands for questions/to volunteer

How we write them I’ve been very particular about how we format our written solutions to these equations: X + 5 = X = 5 Its going to very important in two step equations to keep your equations careful and neat! Work Silently & Independently; silent hands for questions/to volunteer
