Make Your Own "Weather" Map
Students create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar...
Curated OER
Go the Distance
Students work together to build lego cars. They make predictions about how fast they believe the cars will go. They record their observations and discuss their results.
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

A Functional Housing Market
Students access the Internet to search for housing prices in Houston, Texas,(the location can be changed to accommodate any location) and compare the prices to the number of square feet found in the living area of a house.
Curated OER
Properties of Fractals
Students build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by trial...

Absolute Value Equations and Inequalities
Young scholars explore the concept of absolute value inequalities and equations. In this absolute value inequalities and equations instructional activity, students discuss how to solve absolute value inequalities and equations through...
Curated OER
Wing Shapes and Areas
Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.
Curated OER
Calculus
Students make an inquiry with the aid of technology into the concept of functions. The emphasis of the lesson is on the interplay between the geometric and analytic information.
Curated OER
Calculating Range for a Constant Velocity
Students read an explanation from the NASA Web-based "textbook", The Beginner's Guide to Aerodynamics, then use the information in combination with data from other Web sites to solve single variable equations for distance (range), time,...

Math 6 - Act. 08: Patterns
Sixth graders use centimeter cubes to build structures and then compare and contrast the patterns they see.
Curated OER
Modeling Population Growth
Students investigate the reasons for taking a census and determine the problems that are involved in the process. They examine the population figure for Montana and Lake county before using the information to complete the included...
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
Tortillas
Middle schoolers convert recipes for tortillas. They calculate the amounts of ingredients as they convert recipes and write an explanation of the task to demonstrate their calculations. After reviewing their calculations, they...
