finished? do Improving your reasoning skills pg. 150

ObjectiveStudents will review setting up and solving proportions and

use undo tables to solve equations.Students will take notes, work with their groups to solve

problems and present their work to the class.

NOTES— PERCENTS have a denominator of 100 (ALWAYS) Only use percent ratios if you have a PERCENT problem ALWAYS write your units! Use a ratio table to help. THINK about your answer– does it make sense?

Think about different ratios and proportions

AND order of operations (work left to right!work left to right!) Parenthesis (or GROUPINGS) Exponents Multiply OR divide, working left to right Add OR subtract, working left to right

If you were “evaluating”, use PEMA 8 + 2x let x = 4 8 + 2(4) substitute– x is out, 4 is in 8 + 8 multiply 8 + 8 = 16 add

When we “solve” equations we UNDO We use PEMA “in reverse” to find X (X STANDS ALONE)– see undoing chart

practice

1) finish undo tables from last class2) work on chapter review handout with your group----FINISH for homework

Students will be asked to present their work to the class.

Please TAKE NOTES as students present!
