Which requires more water--a bath or a shower? Given some specific criteria, learners attempt to answer the question. A video shows how long it takes to fill a gallon container using a faucet and a shower head. Using that information and...

Many high school science courses rely on mastery of algebra skills. In an integrated chemistry and Algebra II lesson scholars review solving equations for a specified variable with a worksheet. They use common chemistry equations to...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar...

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate...

What does translating points on a number line have to do with solving inequalities? Young mathematicians first learn about translations of points on a number line, and then use this information to solve linear inequalities in one variable.

Allow learners to design their own strategies to solve a problem. Given dimensions of a glass and a smaller marble, scholars must find the dimensions of a larger marble. The answer key suggests using the Pythagorean Theorem, but multiple...

Explore behavior of particles that cannot be seen with a detailed PowerPoint presentation that outlines the basics of electrostatics. The presentation addresses the charge of subatomic particles, conductors and insulators,...

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Proving a trig identity might just be easier than proving your own identity at the airport. Learners first investigate a table of values to determine and prove the addition formulas for sine and cosine. They then use this result to...

Buying enough candy for trick-or-treaters without spending a lot of money can be the ultimate Halloween trick. Middle schoolers solve two holiday-themed word problems to determine which brand of candy is the better deal, based on cost...

Make your money work for you. Future economists learn how to apply sigma notation and how to calculate the sum of a finite geometric series. The skill is essential in determining the future value of a structured savings plan with...

Do some interpretive modeling. Class members watch three examples of interpreting key features of a graph of a quadratic to find solutions to a real-world problem. Learners review how to find the key features on a graph using technology...

By splitting rectangles into four equal parts, scholars practice calculating area and determining side length. They begin by determining the area of each rectangle before segmenting it. Then, they use the space provided to split it into...

Give your learners a small taste of the business world by calculating percent error and percent increase. The resource provides several practice problems to give your mathematicians practice setting up the ratio to convert to percents....

Young scholars investigate the four basic operations of mathematics that are addition, subtraction, multiplication, and division. The use of a technology game is part of the lesson. They demonstrate the proper use of a calculator as part...

An explanation of the Global Positioning System (GPS) and the Geographic Information System (GIS) is given in this presentation. Uses and applications are considered. How it works and sources of error are also touched upon. A large...

Young scholars work with circles, angles and estimating angles in the night sky. In this circles and angles lesson, students practice measuring a degree using the circumference of a circle and apply the degree to determine a way to use...

Using M & M's candies, young statisticians predict the color distribution in a packet of candies and test their predictions against their group and the larger class. A review of converting between fractions, decimals, and percents...

In this integral worksheet, students use double integration to find area and volume. They identify the limits of a sequence. This one-page worksheet contains 11 problems.

Practice addition, subtraction, multiplication, and division using tiles as manipulatives. In this math operations lesson, young learners choose the appropriate sized tiles, arrange them according to directions given by the teacher, and...

Activate your geometer's minds with area calculations, some of which are tricky. First, they solve five word problems dealing only with rectangular shapes. The next five use irregular shapes with side measurements given. Scholars solve...

First graders are introduced to calculators. They complete a variety of math problems using calculators and identify basic parts on a calculator.

In this graphing calculator worksheet for the TI-83 calculator, middle schoolers first observe a demonstration for calculating negative numbers. Next, students use their graphing calculator to answer 6 thoughtful T/F and short answer...
