Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting...

Middle and high schoolers listen to a scenario about a puppy and use the scenario to develop formulas in order to find the area of a circle. For this circumference lesson, pupils understand how to find the radius, diameter, area of a...

Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second lesson in a series of nine. They...

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...

High schoolers investigate linear equations as they use technology (Cabri, Jr.) to explore the equations of lines in slope-intercept form. The technology allows learners to manipulate the line and observe the changes in the parameters of...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Students discuss and experiment with the phases of water.  In this phases of matter lesson, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

Students explore the concept of ratios. They observe a website of Trident Gum that gives a real life example of ratios. Students practice ratio problems in three forms. They express ratios as a proportion and solve proportions using...

Introduce your class to map projections and coordinates, the basics for the work done in a GIS, with an activity that uses Google Earth to challenge learners to think about the earth's shape. 

Learners explore statistics by completing a graphing activity. In this data analysis lesson, students define a list of mathematical vocabulary terms before unpacking a box of raisins. Learners utilize the raisins to plot data on a line...

Students solve problems by finding the radius or diameter. In this geometry lesson, students identify the tangent line of a circle and use properties of circles to find the radius. They relate circles to the real world.

Sixth graders use yarn, paper plate, and other materials to identify parts of a circle. In this parts of a circle lesson plan, 6th graders identify the circumference, radius, diameter, and other parts of a circle.

Students determine location by using the technique of triangulation. They imagine that they are out in the wilderness and have come to the top of a ridge. How can one identify the ridge on the topo map? How can one figure out where you...

Students investigate the derivative of a function.  In this calculus lesson plan, students explore the derivatives of sine, cosine, natural log, and natural exponential functions.  The lesson plan promotes the idea of the...

What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson plan of seven is devoted to logarithms and their properties.

Is GIS the real manifestation of Harry Potter's Marauders Map? Introduce your class to the history of geographic information systems (GIS), the technology that allows for easy use of spatial information, with a resource that teaches...

Students investigate trigonometry.  In this Algebra II/Pre-calculus/Trigonometry instructional activity, students explore Islamic achievements in mathematics as they calculate angles and distances using the Law of Sines and the Law...

Derive tangent lines through derivatives. Scholars use an app to graph functions and investigate derivatives and tangent lines. The interactive automatically graphs a tangent line at a specified point and can also produce tables of values.

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...
