2. Area and Perimeter Formula Drill
3. WinPlot Overview

OBJECTIVE: 1.5.1 Apply knowledge of linear relationships to recognize, extend, and/or create patterns in tables and graphs. 1.5.2 Determine a rule for linear patterns and sequences with combinations of two operations in the rule. 4.2.2 Represent numerical, measurement, geometric, probability, statistical, and/or algebraic information in graphs or other appropriate forms. 5.1.2 Relate and use different mathematical models and representations of the same situation. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms. ACTIVITIES/ASSESSMENT: Continue a review of creating data tables from equations of the form y=mx+b; Review the process for WinPlot on the computers. NOTES: HOMEWORK: Make a data table of y=2.5x+0.25 from -3 to +3 values of x

4. P62 Problem 5.1 Plotting the 4 sets (x=-5 to +5)

OBJECTIVE: 1.5.1 Apply knowledge of linear relationships to recognize, extend, and/or create patterns in tables and graphs. 1.5.2 Determine a rule for linear patterns and sequences with combinations of two operations in the rule. 4.2.2 Represent numerical, measurement, geometric, probability, statistical, and/or algebraic information in graphs or other appropriate forms. 5.1.2 Relate and use different mathematical models and representations of the same situation. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms. ACTIVITIES/ASSESSMENT: Introduce and review equations and expressions. Problem 5.1 is modified to be more in alignment with WASL specifications and the requirements of Algebra. Students will be expected to make tables from equations by substitution then to plot these data on a chart in sets of three. Technology available will mean students will also plot using a graphing program (not Excel). NOTES: WinPlot is a free graphing program. NOTES: HOMEWORK: P137 #4 (handout)
