Brian, Lesson Plan

Target Audience: Geometry Class grades 8-12 mainly 9-10

Big Idea: Using sketchpad to show relationship between geometric drawing and construction

Goal: Using sketchpad, have the students go up to it and draw a geometric figure without the use of a ruler or compass and have each of them compare the drawing. Teach the students the different between drawing a geometric figure and constructing a geometric figure. This will help them learn that precise geometric construction is important when calculating parts of geometric figures like circumference.

Standards addressed:
G.1.2 Construct congruent segments and angles, angle bisectors, and parallel and perpendicular lines using a straight edge and compass, explaining and justifying the process used.
G.4.3 Construct triangles congruent to given triangles,
G.6.4 Construct tangents to circles and circumscribe and inscribe circles
G.8.9 Perform basic constructions, describing and justifying the procedures used. Distinguish between constructing and drawing geometric figures.

Target Audience: Algebra 2 Class Grades 10-12

Big Idea: Using Microsoft excel to construct graph of cost/profit margins involving CDs

Goals: This is a lesson to get students to build graphs using Microsoft excel using cost and profit to determine the optimal price to sell a CD at for the highest profit. The students will hopefully get a better grasp on several concepts including Modeling, Function Graphing, Quadratic and Linear Relations, Data Collect and Analysis, Best-fit Lines, Analysis and Interpretation of Graphs, and Optimization


Standards:
A2.2.4 Find a linear equation that models a data set using the median fit method and use the model to make predictions

Target Audience: Pre-Calculus class Grades 11-12

Big Idea: Having students learn about probability and chance by constructing graphs on Microsoft excel to show the outcome of various experiments

Goals: Have students learn more about factorials and other mathematical processes to determine a correlation to chance and the increase of variables involved in a situation

Standards: PC.9.1 Use a variety of problem-solving strategies, such as drawing a diagram, guess-and-check, solving a simpler problem, examining simpler problems, and working backwards
