Nerding Out with Math

This power point guides students through building a clinometer using a protractor and every day supplies, has demonstrations of the correct way to use the clinometer and the incorrect way. The last several slides of the power point can be printed as a handout for the students so that they can record their measurements while outside. It also includes a work space for the students to show their work and a rubric at the end for how they will be graded.

This is a self-guided booklet for helping students discover how transformations of geometric figures in the plane affect the coordinates of the figures. Students follow directions that allow them to create the formulas on their own, although it easily allows for teacher intervention if necessary.

This is a whole class activity in which each student has a card. One student starts the game by reading the bottom half of their card. Ex: "Who has a line parallel to y = 2x + 4?" and the entire class reads the top half of their cards to see who has the correct answer to the query. The student with the correct card reads theirs in its entirety ("I have y = 2x - 6. Who has a line perpendicular to y - 3 = -7(x + 1)?") and the process starts over until the student that began the game has read the t
