Here's a resource teachers won't want to wash their hands of. Given a task where a full bar of soap is on one side of a balance and 3/4 of a bar of soup and a 3/4-ounce weight is on the other side, young mathematicians must determine the...

Positive or negative, zero or no solution, are all possibilities for the solution of a linear equation. Here the resource gives examples of linear equations in one variable and their type of solutions. The resource comes with commentary...

Have young mathematicians create new identities! They explore the even/odd, cofunction, and periodicity identities through an analysis of tables and graph. Next, learners discover the relationships while strengthening their...

An outbreak of the swine flu on a school campus has caused an increase in the number of boxes of tissues sold by the school store. In a real-world-modeling activity, pupils use composition of functions to determine how the number of...

Kimi and Jordan have taken summer jobs to supplement their weekly allowances. Kimi earns more per hour than Jordan, but Jordan's weekly allowance is greater. This activity asks students to determine how the incomes of the two workers...

The title of this lesson should be "Algebraic Expressions Four Ways." Not only will your class be translating verbal descriptions of algebraic expressions to symbols, but also working with their geometric interpretation via area as well...

Once you've entered effective search terms, how do you evaluate the results of your search? Through the presentation and activities included here, pupils will examine results pages and determine what guiding information is provided. By...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

Supervise the final drafting of a well-organized paragraph by following the steps outlined in this plan. Using the included sample paragraph as a model, class members brainstorm criteria for quality work and then compose their paragraphs...

Reflection is the best teacher. Using the resource, scholars complete the final part of their end of unit assessment, the fourth section of their storyboard about an invention. Next, they track their progress using a self-reflection...

Students define public domain and provide examples of work in the public domain. They define copyright, provide examples of copyrighted materials, and state the procedure for securing copyright for their own work

In this functions worksheet, students distinguish 9 relations as being a function. Students also complete 6 function problems by substituting given information.

In this tables and relations worksheet, 9th graders solve and complete 13 various types of problems that include graphing. First, they solve each equation for the given variable. Then, students determine the ordered pairs that are...

For this inverse function worksheet, students find the inverse function of given values. This two-page worksheet contains 12 multi-step problems.

In a comprehensive unit of activities, learners explore the five senses. Youngsters discover the many different body parts and their functions that allow humans to have sense of sight, touch, smell, taste, and hearing. The best way to...

Functions as inputs for other functions? After reviewing function notation and how to input values to evaluate functions, class members input functions into functions, essentially determining the composition of functions.

How many ways can you represent solutions to an equation? Guide your class through the process of solving equations and representing solutions. Solutions are described in words, as a solution set, and graphed on a number line....

Seeing functions in nature is a beautiful part of mathematics by analyzing the motion of a dolphin over time. Then take a look at the value of a stock and maximize the profit of a new toy. Explore the application of quadratics by...

Fold, fold, and fold some more. In the first installment of a 35-part module, young mathematicians fold a piece of paper in half until it can not be folded any more. They use the results of this activity to develop functions for the area...

Connect geometric sequences to exponential functions. The 26th installment of a 35-part module has scholars model situations using geometric sequences. Writing recursive and explicit formulas allow scholars to solve problems in context.

If mathematicians know the secret to compound interest, why aren't more of them rich? Young mathematicians explore compound interest with exponential functions in the twenty-seventh installment of a 35-part module. They calculate future...

Ready to share the beauty of the inverse function with your classes? This algebra II lesson guides the discovery of an inverse function through a numerical, graphical, and an algebraic approach. Connections are made between the three,...
