Resource Details


Academic Grade 9 Assessment of Mathematics: Algebra I and Geometry

Test your class, or use this 12 page math packet as chapter review. They solve 21 multiple choice problems which require them to graph linear equations, find the volume of prisms and cones, find unknown angles, and determine the perimeter of triangles.

Two Triangles' Area

Geometry juniors apply the Pythagorean theorem to two triangles to determine a final calculation. 

Algebra 2 Honors/IB Mid-Term Exam

In this mid-term learning exercise, students solve equations dealing with such topics as slope-intercept, quadratic equations, symmetry, writing algebraic equations, matrix, functions, combinations, and inequalities.  This 51-page learning exercise contains 80 multiple-choice problems.  Answers are provided at the end of the problems.

45-45-90 Triangles

The process for calculating values using a right triangle with angles of 45 degrees is covered in this third portion of the Pythagorean Theorem series. Here, Sal uses algebra to calculate the value of an angle. The solution to the sample problems involves a complicated resolution. As a result, it would be helpful in preparing for the SAT.
