1. Warmup:
Unit 3 Workbook page 18 #1-6 ALL
and place Interims face down on the front table.
Check using document camera

3. Powerful Tens: a Practice Task
M3U3D3
Powerful Tens: a Practice Task
Objective:
For exponential models, express as a logarithm the solution to abct = d where a, c, and d are
numbers and the base b is 2, 10, or e; evaluate the logarithm using technology.
Essential Question: How can we use tables, graphs, and algebraic reasoning to help us solve exponential and logarithmic equations?

4. Assign p. 15-17 #1-3, 7-12 in card pairs
Begin by reminding students about the process required to evaluate functions.
Assign p #1-3, 7-12 in card pairs
Begin exploration by discussing:
94.87 = 3(10x)
Evaluate functions using tables, equations, diagrams, and graphs
*In this task they will be using tables and graphs to work in reverse, finding the x
value for a given y.
Before checking assignment, discuss:
3 = log(x+3)

5. Then discuss the graph in #4: y = 10-x
Check CW:
Then discuss the graph in #4: y = 10-x
Ask students to solve y = 10-x algebraically.
40 = 10-x
log (40) = log (10-x)
1.602 = -x
= x

6. Check entire assignment using document camera.
Exit Ticket:
Find the solution to each equation.
1] 50 = 5 (10x-1) 2] 102x+1 = 1255

7. Classwork: Homework: p. 15-17 #1-12 p. 19 #9-29 all and
get Interims signed!
