Discover how mathematics can be useful in comparing strategies. Scholars develop probability distributions for situations and calculate expected value. They use their results to identify the best strategy for the situation.

Self-control can seem like such a daunting task, but it doesn't have to be! By participating in this series of small group counseling activities, youngsters learn strategies to help them gain better control of their thoughts...

Young mathematicians solve linear equations by drawing models of algebra tiles using colored pencils. To finish, they solve the same equations algebraically and check their answers using a graphing calculator.

How efficient is a motor in a LEGO set? Future engineers conduct an activity where a LEGO motor-generator system raises an object to a specified height. They then show what they learned and use their measurements to calculate the energy...

Parallel circuits often provide less of a challenge for teens than parallel parking. An installment of a series on parallel electric circuits requires learners to solve increasingly difficult  levels of calculations. Each level...

Determine how close the line is to the scatter plot. Clear video instruction shows how to plot a scatter plot and find the best fit line using the linear regression function on a calculator. Pupils use the information from the calculator...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

How does an input affect an output? Assess your learners' ability to answer this question using this pre-test. Scholars answer questions about the basics of a function. Topics include determining if a table or statement represents a...

Provide pupils with problems to check their understanding of the concepts within the unit. The seven-part series of lessons covers concepts related to irrational numbers. Learners convert between fractions and decimals, estimate the...

Thirty percent of energy used by schools is used inefficiently! Part two in the series of 12 has groups perform energy audits of their schools as part of the Cool Schools Challenge. Each group is assigned a specific room, performs the...

Find the point that splits the data. The lesson presents to scholars the definition of the median through a teacher-led discussion. The pupils use data lists and dot plots to determine the median in sets with even and odd number of data...

Teenagers love to think about driving and buying their first car. The intent of this resource is to create an equation for the list price of a car and add the appropriate state tax. Once your teens understand the calculation, ask them to...

Time to come clean! Scholars continue preparing the shampoo they created in the previous two lessons. The purpose of this stage is to calculate the perfect amount of additive to make the shampoo lather. 

Take an indirect view of proportionality. Using a similar approach of direct variation, the resource shows how to solve inverse proportions. The video steps through finding the constant of proportionality to write the formula for the...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

Many math concepts are covered through this resource: percentages, decimals, ratios, exponential functions, graphing, rounding, order of operations, estimation, and solving equations. Colorful worksheets and a link to a Google search for...

Apply systems of inequalities to a real-world problem. Here, scholars learn to graph solutions to systems of linear inequalities. To finish the lesson, they solve a problem involving burgers and cheeseburgers using a system of inequalities.

More than 90 percent of the people in a building have come down with an illness, and it is your job to investigate. Teachers give scientists the data needed to decide what is important and how they can solve the mystery....

Individuals learn to apply the Euclidean algorithm to find the greatest common factor of two numbers. Additionally, the instructional activity connects greatest common factor to the largest square that can be drawn in a rectangle.

As math scholars begin taking on more complex division problems, it's time to cover the different ways to show remainders. Here, they complete eight long-division equations with a fraction remainder and then eight more with a unit...
