How many Calories one needs on a daily basis is dependent on a number of factors including gender, height, and activity level. In the third of seven lessons about energy and food, young nutritionists calculate the number of Calories...

Learners view a Cyberchase video and participate in a calculation of points exercise. In this summing of positive and negative integers, students calculate the principal character points to see if he can qualify for a contest.

There's no risk of injury when working with virtual HCl! Challenge your young chemists with making calculations to create a 3M solution of HCl from the concentrated acid. They first calculate the correct ratios of HCl and water and then...

As part of an initiative to strengthen our young adults' financial understanding, this problem explores the cost of bread and minimum wage since the 1930s. Learners are asked to find the percent increase from each year and compare it...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Package design is an economic necessity. Young scholars assume the role in an interesting inquiry-based lesson. Given 24 cubic shaped candies to package, they must determine the arrangement that uses the least amount of cardboard to...

Those graphing calculators can be tricky; good thing Texas Instruments has devised a lesson plan on how to use their TI-Nspire calculator to graph functions. Kids investigate functional notation as they graph ordered pairs in the form...

Get out those thinking caps and apply graphing functions to a real-world problem. Use the TI-83 graphing calculator to evaluate algebraic expressions that are imbedded in a series of real-world scenarios. A great lesson!

For use with a TI-nspire calculator, this lesson focuses on adding and subtracting polynomials. Learners use calculator to add and subtract polynomials using both the vertical method horizontal methods. A class discussion follows the...

A presentation on how to calculate percentage is here for you. Young mathematicians gain practice in performing the calculations necessary to find a percentage value. Many excellent tips and problems to solve are embedded in the...

Another good presentation by Christine Berg is here for you. In it, learners are coached on definitions of area and perimeter and are shown how to perform calculations for both. They also see how to calculate the area of a triangle by...

The shortest distance from point A to point B is a straight line—or is it? Young scholars determine the shortest route either along a circular path or through the center of the circle. Learners gain a unique perspective on arc length and...

Scholars crave practical application. Let them use the different models of a quadratic function to plan the size and shape of a school playground. They convert between the different forms and maximize area.

Unscramble a carnival mystery! Scholars observe a video of an overhead view of a carnival ride, The Scrambler. They then must determine mathematically where a specific car will stop after a certain amount of time.

Scholars have an opportunity to use their geometric modeling skills. Pupils determine a reasonable estimate of the number of string beans that would fill the average human body.

Biking may be an outlier. Using data from 10 states on the number of people reporting they bike to work, pupils calculate the measures of center. Scholars determine the range and interquartile range and find which provides a better...

There can be a steep learning curve when teaching about exponential growth, but the lesson helps kids make sense out of the concept. When talking about exponential growth of viruses, learners may not be very interested, but when you are...

Seventh grade math is so much fun! They solve 10 different problems that include using patterns to complete a table, describe the pattern, and identify the specific term in the pattern for each. Then they give a description of the...

Here's how to calculate the areas of polygonal figures. In this measuring area lesson plan, upper graders use hash marks to create and count square units. They also problem solve a cyberchase activity watching Quicktime videos.

Math wizards practice adding fractions with unlike denominators on this simple matching activity. Presented with ten addition expressions, children must calculate the sum of each and match them to the correct...

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...

How much money is enough money? Future wage earners explore the minimum hourly wage and then use it to calculate monthly and yearly earnings. They use an interactive to consider living costs and determine whether earning a minimum wage...

Partners fill out a register to record transactions on a college investment account. They use the amounts listed to calculate the running and current balance of the account, providing experience in adding and subtracting rational numbers.

Challenge the class to calculate unit rates using complex fractions. Pupils work through examples of finding unit rates using ratios of fractions. To complete the 11th lesson plan of 22, scholars review sample work and determine whether...
