Weighted averages can be tricky to explain! However, this study guide makes it easy for teachers by including definitions, explanations, and breaking down problems into three steps. Includes mixture problems and uniform motion problems.

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Ready to study inequalities with your class? Use this activity to solve multi-step inequalities and graph the solutions. The document would be great to use as a study guide as you present the material, or could easily be modified and...

Learners investigate why theoretical probability doesn't always match reality. The activity involves using Python 2.7 (or Sage) to set up a Bernoulli Trial. It also involves setting up a spreadsheet to simulate the Birthday Paradox....

Sixth graders interpret linear and nonlinear graphs. They create graphs based on a problem set. Next, they represent quantitive relationships on a graph and write a story related to graphing.

Introduce a new type of function through discovery. Math learners build an understanding of rational expressions by creating tables and graphing the result. 

Class members build a machine to demonstrate Lenz's law and help this scientific principle come to life. After building a ring fling machine, instructions for properly operating the machine and a few thought-provoking questions lead to...

Students examine the four quadrants of Cartesian coordinate plane. They play maze games and coordinate games to discover how to read and plot points on the plane. Students plot points on the coordinate plane and examine the ratio of...

Students explore functions, function rules, and data tables. They explore terms of linear functions. Students use computers to analyze the functions. Students write short sentences to explain data tables and simple algebraic expressions.

Using their Ti-Nspire to determine the solutions of parabolas, students explore the concept of complex roots.  Students determine if parabolas have real or complex roots.  Students determine the the axis of symmetry and the...

Students analyze data from a virtual field trip to Michigan. They conduct Internet research on mileage and travel time between cities, calculate and compare fuel costs, and research and calculate lodging, activities, and meal costs.

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

High schoolers analyze and interpret data related to the crew and passengers of the Titanic. They research information on a Titanic database to illustrate specific statistical conclusions, and whether or not social status affected the...

In this lesson on a standard form, students explore how to identify and graph a linear equation in standard form.

Convert linear equations in various forms into standard form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
