Literal Equations and Word Problems Review 2015-2016

Objective: To review for tomorrow’s quiz! Warm-Up 1. Pick up an answer key from the front cart and check your pre- assessment corrections **RETURN ANSWER KEYS TO THE FRONT CART WHEN FINISHED** 2. Pick up a Warm-Up Review from the front of the classroom and complete **QUESTS WILL BE RETURNED TODAY!!**

Today’s Agenda: 1. Warm-Up: Check Homework from previous night and go over handout 2. Get Quests Back and other papers! (Go over Quests) 3. White Board Review Reminders: If you have not completed the stations from Monday and Tuesday, you need to come see me during Flex and Lunch to finish them Homework: Study Quiz tomorrow Quest Corrections due Wednesday, October 21st. (You have a full week don’t wait til the last minute)

Corrections Reminders: Quests Averages: P1: 87.2 P3: 87.6 P7: 89.6 Corrections: DUE WEDNESDAY, OCTOBER 21st (Take advantage of the no homework this weekend) Come see me during flex and lunch if you’re not sure of something on this quest! We will be using all of these skills throughout the school year. So make sure you feel very confident in all of them. **Check your answers as I read off the answers, any we need to see specifically? Corrections Reminders: All Quests must be SIGNED All Corrections are on a separate sheet of paper and stapled to the back of the quest (Everyone must do corrections unless you earned a 100%) Corrections MUST include original problem, problem correctly solved AND an EXPLANATION of why you got it wrong (What did you do wrong? Analyze your mistake)

All other papers returned: Exit Tickets from last unit (My goal this unit is to get them back to you by the next day) Matrices Partner Assessment Compound Inequality Activity

The rest of the class we will be doing White Board Practice! One Person from each group grab everyone in your group a white board and sock! Everyone Else: Take out a Marker!
