Scholars first learn the definitions of the sine ratio, the cosine ratio, and the tangent ratio. After mastering these definitions, they use the new information to solve triangles.

There's just something special about lines in algebra. Introduce your classes to linear equations by analyzing the linear relationship. Young mathematicians use input/output pairs to determine the slope and the slope-intercept formula to...

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

Groups sort through NASA data provided in a graphic to create a graph using uniform units and intervals. Individuals then make connections to the increasing, decreasing, and constant intervals of the graph and relate these...

The third in a series of 10 STEM project-based lessons focuses on cells types, functions, and physiology. Through research, discussions, writings, and presentations, groups learn about the difference between plant and animal cells, the...

DNA carries the codes for creating just the right protein. A well-designed lesson leads pupils through the process from start to finish and everywhere in between. Guiding questions with supporting video help scholars understand the...

Although there are only 16 questions here, this chemistry handout makes a terrific unit assessment. It queries youngsters on the properties of ionic and covalent compounds, relates bond length tho stability and enrgy, compares polar and...

Here is a study guide that breaks graphing quadratic functions into three simple steps. Quadratic functions in vertex and intercept form are included. Use during a lesson or afterward for skills practice. Note: Make sure your class has...

Master word analogies with a straightforward exercise. Pupils match word pairs to one another based on the relationships represented in each pair. The worksheet provides bridge sentences that learners fill out as they determine the...

Multiplication in polar form is nice and neat—that is not the case for coordinate representation. Multiplication by a complex number results in a dilation and a rotation in the plane. The formulas to show the dilation and rotation are...

Make an informed decision when choosing a medical insurance provider. An engaging lesson asks your classes to write piecewise models to represent the cost of different medical plans. The project-based learning activity is a variation of...

Animating an object by moving it across a computer screen can be accomplished by drawing the object repetitively, each time adjusting some aspect of the drawing slightly. This activity is an easy introduction to animation in JavaScript,...

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

After partnering up each person, give the pair a ball. One person gets the ball first, while the other person runs around. The person with the ball tries to chase down their partner and hit them with the ball. Then, the roles reverse....

Enhance pupil understanding of proportions and variable relationships by studying direct and inverse variation. Use the idea of a proportional relationship to teach direct variation. Then use a similar pattern to help individuals...

Complex solutions are not always simple to find. In the fourth lesson of the unit, the class extends their understanding of complex numbers in order to solve and check the solutions to a rational equation presented in the first lesson....
