1. Do-Now Solve the following equations: 1). 3X – 10 = 142). 2B + 10 = 30 3). X/3 + 16 = 204). A/3 - 9 = 21 5). 4V + 12 = 606). -2Z + 24 = 60 HERO PROBLEM: -14Y + 28 = 168 COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY

2. Objective & EU Today we play numbered heads OBJECTIVE: SWBAT solve one and two step equations by using inverse operations to isolate the variable. Essential Understanding: Our knowledge of math must extend towards applying it correctly under time pressure. What are we doing? Why are we doing it? WHEN FINISHED SIT IN ACADEMIC POSTURE!

3. Thinking Question Why does timing a problem make it harder? What strategies can we use to make it easier? Silently think about the answer & jot down your ideas WHEN FINISHED SIT IN ACADEMIC POSTURE!
