1. On Desk: 1. Pencil 2. Math Journal 3. WDYE Learning Log 4. Parent Sig. on WDYE Quiz? Learning Log: 1. HW: p. 61 #9-13 (need list) #31-36 2.Math XL: Mid Year Assessment due by Friday, Jan. 29 th ! 3.ISD Common Assessment – Th & Fri. Math CC7/8 – Be Prepared

2. Warm Up Lesson 3.3 – Analyzing a Game – Roller Derby! Begin HW? Tasks for Today

3. Warm Up George has a bag with 12 yellow marbles, 6 green marbles, 8 purple marbles, and 4 blue marbles. If he wants the probability of picking a yellow marble to be ½, what should George do?

4. Warm Up 2. Solve the equation. Show all your steps. 5 (4 – 2x) + 3 = -7 2) x = 3

6. Use labsheet 3.3 under doc camera – Students against Teacher Have a student volunteer record dice and sum on board

8. What might be a good way to organize this data? A table?! Let’s do it together. (You’ll need this for tonight’s HW!)

9. Sum of Two Dice Cube #1 Cube #2 1 2 3 4 5 6 12 34 5 6

10. Sum of Two Dice - KEY 36 possible outcomes Only 11 different possible sums

11. No… Only one! P (sum of 4) = 3/36 = 1/12 (1+3, 3+1, 2+2) P (sum of 6) = 5/36 (1+5, 5+1, 2+4, 4+2, 3+3) The sum of 7 occurs most often. (6 times) The sum of 6 and 8 occur next most often. (5 times)

12. There are more ways to get sums that are close to the middle numbers (6, 7, 8), so the markers should be clustered toward the middle!
