Learners explore area of polygons and regular polygons in this math lesson. They calculate the area of several polygons using Cabri Jr. and analyze shapes and write formulas to solve for the area.

How do we measure the deviation of data points from the mean? An enriching activity walks your class through the steps to calculate the standard deviation. Guiding questions connect the steps to the context, so the process...

Finding the volume is an integral characteristic of a vase. Using the idea that summing the areas of cross-sectional disks will calculate the volume of a rotational solid, pupils find the volume of a vase. Scholars determine the interval...

The area is essential to volume. As part of the review for the General Certificate of Secondary Education math assessment, a helpful video covers how to find the volume of several common 3-D figures. Pupils use the general volume formula...

Investigate the different types of slope using graphs and ordered pairs. Scholars use the slope formula to determine the slope of a line between two points. Includes examples with a slope of zero and with no slope. The lesson follows a...

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...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Slip sliding away. Groups investigates the two types of friction by running an experiment that allows them to calculate the coefficient of static friction and the coefficient of kinetic friction. The experiment uses a box, a...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

Explore the power of mathematics through this two-week statistics unit. Pupils learn about several climate-related issues and complete surveys that communicate their perceptions. They graph both univariate and bivariate data and use...

Your classroom will be rockin' during an toe-tapping lesson! Dave Matthews inspires a lesson on proportions as youth listen to a song and predict its length. Lesson materials provide learners with ordered pairs that mark the time slider...

Students, while in the computer lab working on a spreadsheet program, calculate interest and accumulated value of a savings plan. They follow specific directives on how to create their spreadsheets. At the end of the lesson they print...

Almost every teen wants a car, but can they really afford one? The lesson walks pupils through how to identify a budget, find all of the costs associated with car ownership, and determine if they should buy the car or keep looking.

Does your bank pay you for allowing them to hold your money? Class members research three different ways they can earn money using money already in the bank. Topics include certificates of deposit, statement savings accounts, and...

Students use Excel spreadsheets to organize purchases, discounts, sales prices, and sales tax. Students follow step by step instructions and enter formulas as well as use the auto sum feature to calculate required calculations.

In this quantities in chemistry instructional activity, students solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and...

Teach your pupils to calculate the area of different polygons. Learners create formulas to solve their problems. They use the TI navigator to graph their shapes and observe the change in area.

Oh that intercept! Budding algebra masters solve linear equations from standard to intercept form. They identify the slope and y-intercept to help graph the lines, an then create coordinate pairs using a table of values. Great TI tips...
