Students explore the concept that when money is borrowed, people pay to use it because someone else is losing an opportunity to use it while they have it. What you pay to use the money is called interest. The rate of interest is a...

In this volume learning exercise, students answer four multiple choice and four problems solving problems regarding the volume of a trench.  Examples, formulas, explanations, and answers are provided.

In this geometry worksheet, 6th graders calculate the area of triangles and trapezoids using the given formulas. They use the formulas to find measurements of lines that are part of the triangles and trapezoids.

In this online math instructional activity, students determine the radius, circumference, diameter and area of circles. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

Young scholars calculate the midpoint of a line. In this geometry lesson, students identify the different parts of the coordinate plane. They use the midpoint formula to find the middle of segments between a pair of coordinates.

In this acid and base worksheet, students fill in a table with the type of acid or base and the symbol used in calculations. Types of acids and bases identified include strong acids, weak acids, strong bases, weak bases, Lewis acids, or...

In this acid and base worksheet, students fill in a table given acids and bases and identify the type of acid or base it is and the symbol used in calculations.

Eighth graders use their knowledge of calculating the volume of cylinders to calculate the volume of trees. For this volume lesson plan, 8th graders identify why calculating the volume of cylinders would be valuable to a forester.

Young scholars explain the formula for finding the area of a paralellogram and its relation to the area of a rectangle. Finally, they construct the formula for the area of a paralellogram.

Students evaluate mathematical problems using the formulas for volume. They recognize "perspective" in different shapes including cubes, pyramids and cylinders. Students practice on brainstorming all the different shapes and how they can...

Students apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. Students define the use...

Students calculate the density of regular and irregular solids and liquids. They relate the term dense to science as well as its literal meaning that society uses it as everyday. A worksheet is completed on density.
