One of the most common, everyday applications of math is dealing with money. This single problem calculating how much change Margie receives is more involved than it appears at first glance. An understanding of how fractions and decimals...

Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

The volume of a fish tank is a rather important measure when it comes to building an aquarium for different species of fish. In this problem, your kids look at how many different ways they can make a fish tank of a specific volume,...

Learners graph and order numbers using a number line. They also solve word problems using fractions and decimals and rewrite equations to solve problems correctly. Several example word problems are given. 

How can mathematics help scholars choose a college? High schoolers learn how they can use decision matrices to rank colleges based on selected criteria. They also see how to weigh criteria using multiplication of the decision matrix by a...

Scholars take transformations from the second to the third dimension as they extend their thinking of transformations to include three-dimensional figures. They explore how to use matrices to represent compositions of...

Students define the counting principle and how it relates to integers. In this algebra lesson, students add and subtract using the addition and multiplication principles. They solve problems using combination and permutations.

Learners solve problems using matrices. In this algebra lesson, students add, subtract and multiply matrices. They use the graphing calculator to simplify and graph linear equations.

Fifth graders identify a set of data from a real world problem. In this statistics lesson plan, 5th graders identify the range, mode, median and mean using some manipulatives. They write words randomizing the letters.

Students solve problems with compound inequalities. In this algebra lesson, students solve inequalities using addition, subtraction, multiplication and division. They graph-their solutions on a numbers line.

A question to ask your class is, How fast is your Internet? That depends on the data transfer rate (DTR), which is the unit rate used in this activity. Math students will calculate how long it takes to download a music file and a video...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students convert from Celsius to Fahrenheit. In this converting activity, students explore temperature conversions. They use a thermometer to determine the temperature of given items.

Students examine population growth and collect data. In this statistics lesson plan, students create a scatter plot to represent the different species found in the water and are being harvested. They graph their data and draw conclusion...

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their ciphers...
