Flashcards to accompany Ch. 1 of the Discovering Geometry textbook.
PowerPoint drill practice of triangle types for Discovering Geometry Lesson 1.5
These slides scaffold discussion, easing students from simple modeling to a complicated problem represented by a quadratic expression. It can be a good supplement for section 1.4 in Carnegie Learning Algebra I or section 2.3 in Discovering Geometry by Key Curriculum Press.
This lesson goes with Section 2.6 of the Discovering Geometry textbook, but you could use it with any book.
Group Size: Any
Learning Objectives:
Students will be able to identify special angles on parallel lines and will discover and apply conjectures about these angle pairs.
Guiding Question:
When two parallel lines are cut by a transversal, how are the angles related?
Materials:
Tracing paper is best cut into little squares is best. Patty paper is ok. Student copies of the investigation handout. Multimedia projector if you want to show the powerpoint presentation.
Procedures:
1). Begin with direct instruction on the vocabulary of:
- Transversal
- Corresponding Angles
- Alternate Interior Angles
- Alternate Exterior Angles
Assessment:
Homework questions from the book.

Lesson plan for a hands on approach to teaching triangle inequalities
Powerpoint with review questions and pictures to supplement teaching the Triangle Inequality Theorem
In this game, students will roll a set of dice a total of 36 times. Player A gets 1 point if the sum is odd, Player B gets 1 point if the sum is even. The player with the most points at the end of the game wins. Do you think this is fair? Play to find out.
The rules are the same in this game as in the Addition Game, only this time instead of the sum the students are getting the product of the two dice.
The questions here ask the students to compute what the experimental and theoretical probability are and whether or not they thought the game was fair. It also brings up some different rules that other students have played by and they must respond whether they think those rules are fair or not and why.
In this review students will answer questions based on the vocabulary they have learned so far in their probability unit.
Students will answer questions based on experimental probability as well as answer a question about who will win a game based on data that is given.
