1. Do Now Solve the following problems using PEMDAS - Remember to number the operations! 1). 24 – 8 x 2 + 6 = 2). (6 + 4 2 ) ÷ 2 + 6 = 3). (12 – 2 x 4) 2 ÷ 4 + 5= 4). 6 – 4 + 8 x 2 = COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY DURING REVIEW I WILL ASK FOR VOLUNTEERS TO SOLVE THESE! EVERYONE ELSE PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

2. Objective & EU OBJECTIVE: SWBAT answer questions on evaluating expressions ESSENTIAL UNDERSTANDING: It is easy if you go slowly and carefully. Follow PEMDAS! This is what are focusing on today! Come out of this lesson with your essential understanding!
