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.
Student-centered investigations on Special Angles on Parallel Lines. Students use tracing paper (or patty paper) to create conjectures about corresponding angles, alternate interior angles, and alternate exterior angles.
Students use a formula to solve problems provided by Mesa College’s Veterinary Program. This requires the use of subscript notation and the multiplication property of equality to solve. The equations are the simplest of linear equations however the application makes them more interesting.
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 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.
