Math Counts

This is a unit designed for a level 1/AP high school geometry course. There are 27 documents that include rigorous problems with the task of finding the area or perimeter/circumference of triangles, trapezoids, kites, and circles. Students must use the pythagorean theorem to find the missing height of a trapezoid, and even the quadratic formula to find x in a triangle diagram. Circle problems may give the area and students have to find the circumference. Included are warmups, a powerpoint, a p

This unit includes 14 documents; explorations on reflections, rotations, and translations, 2 follow-up quizzes (one for reflections and one for rotations), a practice unit test with answers, and a unit test. Students are asked to investigate slopes and segment lengths to discover preservation of orientation and size. Students will also discover that points reflected over the line y=x are equidistant from the line. They will discover that the line which connects a point to its reflection over

This unit is designed for a level 1 or AP Geometry class. It includes 10 documents: warmups, worksheets, powerpoint, a quiz and test. The unit covers everything from basic terms like complementary, supplementary, vertical, linear, and congruent angles, to the angle addition postulate and finding the missing angle measures by solving a system of equations. There are also word problems like, "The complement of an angle is 3 more than 5 times the original angle. Find the measure of both angles

This unit is an introduction to a level 1 Geometry course on proofs. Students will learn all properties of equality including the transitive, symmetric and reflexive properties of equality. The goal of most proofs in this unit is to prove the measure of an angle. Students should know what congruent, supplementary and complementary angles are before attempting these proofs. Included in this unit is a powerpoint, worksheets, and quizzes.
