This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

Calculate the movement and properties of planets like professional astronomers! Scholars use Kepler's third law to find Mercury and Venus's distance from the sun. Using changes in brightness of distant stars and Kepler's third law,...

Don't cross the line; just walk along it. Scholars investigate a scenario in which a person starts at zero on a number line, then moves left or right depending on a flip of a coin. They determine the number of outcomes for six flips,...

Shake up things in the classroom. The unit uses earthquakes to bring a real-life connection to finding arc lengths, logarithms, and equations of circles. Small groups determine whether particular towns would have felt an earthquake after...

Investigate patterns in the binomial theorem. Pupils begin by reviewing the coefficients from Pascal's triangle. They look at the individual terms, the sums of the coefficients on a row, and the alternating sum of each row. Individuals...

Fly through graphing functions with the Function Flyer. Young mathematicians use an interactive to graph different types of functions. A set of exploration questions has users investigate patterns in functions.

After investigating the US Environmental Protection Agency's climate change website, your environmental studies students discuss greenhouse gas emissions. They use an online interactive tool to look at data from power production...

Probability, especially conditional probability, can be a slippery concept for young statisticians.  Statements that seem self-evident on the surface often require a daunting amount of calculations to explicate, or turn out to be...

To understand an informal derivation of the formula to find the volume of a sphere, young mathematicians investigate the volume of a sphere about the volume of a right circular cylinder. They develop the formula for the volume of a...

Math scholars investigate the cost of living in Hong Kong compared to Chicago but must first convert the different types of currency. They then choose a type of graph to compare different spending categories and finish the activity by...

Investigate the construction of the electric circuit with a thorough presentation that provides a solid background for each type of circuit. After introducing key vocabulary, the lesson goes on to explain circuit design.

Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

Lather is not necessary for an effective shampoo. After learning of the industry created consumer misinformation, individuals investigate the toxicity of the most popular additive in shampoos to create lather. They use their results to...

Lead your class on a search for precious bones. Using a presentation, the class investigates the golden ratio in art and nature. Groups of pupils measure specific bones and find the average ratio for the class. To further cement the...

Textbook problems with a twist! Young chemists analyze an ionic reaction to identify the limiting reagent. They then make calculations to determine the concentration of unknown solutions. Finally, they put their work to the test and...

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

Ready to increase pupils' understanding of slope with an upward slope? Scholars use an interactive that allows users to move two points on a coordinate plane. The interactive then automatically calculates the slope, the slope-intercept...

Pupils gather measurements of real-world objects that have slopes. They then plot the measurements and find an equation of a line that fits the measurements. Finally, groups investigate the ADA and determine whether different ramps meet...

Don't be fooled: the taller glass doesn't always hold the most. Given the dimensions of different cylindrical containers for beverages and popcorn, pupils calculate the volumes. They see how changing the dimensions affects the volume and...

Develop a sense of normal. Learners develop two questions to ask classmates to gather numerical data before creating a box and whisker plot and a histogram to display their data. Class members make inferences and investigate the data...

Using a home-built hydrophone, pupils investigate how things sound in water. Learners listen to sounds created in air and then compare that to the same sound picked up by the hydrophone. Individuals compare the loudness and the pitch of...

Scholars complete the California CareerZone's Quick Assessment to identify their dream job. The assessment calculates responses to provide a list of careers. Learners choose one from their list and discuss it with their peers.
