Ninth graders know how to solve a system of linear equations, but what happens when the system involves an exponential function? The instructional slideshow teaches viewers to determine solutions to systems of equations with linear...

What happens when rotating an image 180 degrees? The sixth lesson in the series of 18 takes a look at this question. Learners discover the pattern associated with 180-degree rotations. They then use transparency paper to perform the...

Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

What makes a function a function? Learn the criteria for a relation defined as a function both numerically and graphically. Once young mathematicians define a function, they use function notation to evaluate it. 

Demonstrate the meaning of an absolute inequality using three different methods. Here, scholars explore absolute value inequalities through graphing, number line distance, and compound inequalities. Pupils complete various activities to...

Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

In this Algebra/Algebra II worksheet, students find and graph the solution of an inequality.  The two page worksheet contains a combination of eleven multiple choice and free response problems.  Answers are provided. 

This comprehensive unit on linear and exponential functions provides numerous clearly-written worksheets. Topics include graphing linear equations, solving systems of equations algebraically and by graphing, identifying the domain and...

This site gives a description of intersection of sets along with an example. There are links to related terms, challenging problems, more information, and the interactive check point involving set intersections located in the left-hand...

This page gives a brief discussion of the intersection of sets in mathematics and probability.

This resource explains concepts related to set notation and gives examples for each.

This page provides a good explanation of unions of sets in mathematics. It discusses the union of disjoint sets and the probabilities of unions, incorporating probabilities of the two independent sets and their intersection. Discusses...
