Creating and Graphing Linear Equations in Two Variables
This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is taken to discuss...

Curb the Epidemic!
Class members use an applet on the Internet to simulate the spread of a disease. The simulation allows individuals to determine two nodes to vaccinate to limit the number of nodes infected. By running several simulations, scholars can...

Scientific Notation II: The Mantissa
Practice converting a conventional number into scientific notation, and vice-versa. Using an applet, they perform the operations of multiplication and division on numbers expressed in scientific notation.

Solving Exponential Equations
Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential equations after...

Creating Linear Equations in One Variable
The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....

Photosynthesis
Venus fly traps photosynthesize and consume insects because the soil they live in does not provide enough nutrients. Scholars analyze historical scientific experiments to learn how scientists discovered photosynthesis. From their...
Illustrative Mathematics
Finding an Unknown Angle
Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

The Reasons for the Season
Students explain the reason for the changes in season. For this lesson examining the relationship between the Earth and the Sun, students use an applet to discover how the alignment of the Earth and the Sun cause the change in seasons.
Curated OER
Planet Interiors
Students view cut-away images of the planets' interiors, comparing and contrasting them with the Earth's in written form. Students also classify each planet as "terrestrial" or "Jovian". The Planet Interiors applet on the CSA website...
