Nov 16 (P)/ Nov 17 (W) Take papers from group folder and put in your notebook. Do Warm Up sheet on your table

Due today pg. 225, # 2 and 4 Following Families on the Trail Please get your work out and place on your desk.

Due Next Class pg The Basic Student Budget BRING GRAPH PAPER NOTE- MIDUNIT TEST Friday, Nov 20 (P) Monday, Nov 23 (W)

Agenda Warm Up/ Announcements Practice- Scaling Graphs; Finding slope from a table and from a graph Debrief Who Will Make It? Pg. 221 Mystery Bags Game, pg

Objective Students will be able to find rules from graphs; students will be able to use mystery bag model to solve basic equations

debrief pg 225, 2&4 1) what is your rule for each family? 2) how can you see how much they started with in the graph? the rule? 3) how can you see how much they used each day in the graph? in the rule? 4) is there a time they will ever have the same amount of coffee? why not?

pg. 221 Who Will Make It? Circle points on the crosshairs. Find slope using a slope triangle and an in/out table. Complete the handout.

Scaling/Slope practice Finish your worksheet Breakout groups. All papers will be collected in 20 minutes.

Review finding rules ….notes 1. Where does it begin? “b” 2. Is the middle increasing or decreasing? “±” which means “+” or “-” (plus or minus) 3. By how much? “m” EQUATION or RULE: y = b ± mx

How do we find slope? Slope Triangles OR In/out tables Select points from YOUR LINE that are on the “crosshairs” to minimize estimating!! CIRCLE these points on your graph– this is part of showing your work!! SLOPE is defined as change in vertical units divided by the change in the horizontal units or change in the out divided by change in the in

Mystery Bags Game, pg Read page 252 together Do # 1 together as a class. Remember– each bag weighs the same! - the pans must balance exactly! FINISH 1 – 8 in your notes. Draw a diagram for each problem. Be ready to present on white boards.

Exit Quiz Put away all supplies and straighten desks. Complete the quiz given on a handout. Submit in your group folder: 1. homework 2. all graphs and class work 3. exit quiz
