Ann's Lesson Plans

Lesson Plan #1

Target Audience: High School Geometry Class (10th-12th grade)

Big Idea: Using Geometer’s Sketchpad to construct different quadrilaterals and also use it to discuss the similarities and the differences between them.

Goal: For students to learn how to construct the different types of “special quadrilaterals.” Also, have them make conjectures about each quadrilateral and their diagonals.

Standards:
- G.3.1 Describe, classify, and understand relationships among the quadrilaterals square, rectangle, rhombus, parallelogram, trapezoid, and kite.
- G.8.3 Make conjectures about geometric ideas. Distinguish between information that supports a conjecture and the proof of a conjecture.

Lesson Plan #2

Target Audience: High School Algebra II Class (10th-12th grade)

Big Idea: How to model exponential decay and exponential growth and also, using a graphing calculator to show either growth or decay.

Goal: For students to understand what exponential growth and decay means. How to model exponential decay and growth with real world problems. To teach the students the proper way to graph these models on a graphing calculator.

Standards:
- A2.7.1 Graph exponential functions

- A2.7.8 Solve word problems involving applications of exponential functions to growth and decay.

Lesson Plan #3

Target Audience: High School Algebra II Class(10th-12th grade)

Big Idea: Using a graphing calculator to graph inequalities and also to solve systems of quadratic inequalities.

Goal: For the students to understand how to graph inequalities using a graphing calculator and also what they will look like, what area to shade for example. The students will also learn how to solve systems of inequalities and they will understand the meaning of the graphs.

Standards:
-A2.2.3 Use systems of linear equations and inequalities to solve word problems.

-A2.2.1 Graph absolute value equations and inequalities.
