Ninth graders solve quadratic equations. In this factoring lesson plan, 9th graders answer questions from the text and complete a worksheet. 

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Investigate the order of operations! Learners participate in interactive multi-media activities to examine and solve multi-step equations, inequalities. They evaluate formulas and simplify monomials and polynomials.

Tables are useful for more than just eating. Learners use tables to organize data and calculate probabilities and conditional probabilities. 

Everything you could possibly want to know about quadratic equations, all in one resource. Instructors demonstrate how to translate between different forms of quadratics (equation, table of values, graph, verbal description) and finding...

It is all relative, or is it all conditional? Using an exploration method, the class determines whether there is an association between gender and superpower wish through the use of calculating conditional relative frequencies. The...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Can an equation have an infinite number of solutions? Allow your class to discover the relationship between the input and output variables in a two-variable equation. Class members explore the concept through tables and graphs and...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Life isn't fair ... like inequalities. After first reviewing inequality symbols and how to read inequality statements, learners discover how to solve one-step inequalities and graph their solution sets.

There's more than one way to solve an equation — three, actually. Scholars learn how to solve simple linear equations in one variable using three different methods, which include using balance scales, using decomposition (e.g., turning...

Explore functions with non-constant rates of change. The first installment of a 12-part module teaches young mathematicians about the concept of a function. They investigate instances where functions do not have a constant rate of change.

Eighth graders practice calculating problems using addition, subtraction, multiplication and division. They estimate solutions to algebraic problems. They also graph their solutions.

Students develop the concept of supply and demand. For this economics lesson, students listen to a lecture and take notes on supply and demand. Students create a coherent set of notes about supply and demand.

Students explore the concept of running a business. In this running a business instructional activity, students put their plan of action into practice. Students market a product and try to maximize profit.

Students construct spreadsheets from raw data. In this spreadsheet construction lesson, students compile data into Microsoft Excel. Students familiarize themselves with entering and presenting data in a spreadsheet.

Young scholars explore the concept of multi-step equations. In the multi-step equation lesson, students solve equations by the 'party method'. Young scholars make a flip book that shows the steps in solving multi-step equations.

Ninth graders investigate the concept of relations and interpret graphs and tables. They analyze given data and look for a pattern to determine if the numbers represent a function. Students practice solving scientific word problems that...

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Sixth graders explore the relationship between area and perimeter of rectangles. In this area and perimeter lesson, 6th graders measure and determine perimeter and area of various rectangles. Students create rectangles with given areas...

Practice factoring numbers by using graph paper, manipulatives and computer applets.

Turn young scholars into detectives as they decipher encrypted messages.  Introduce your class to modular arithmetic and have a little fun encrypting and decoding secret messages. The activity does not hit many content standards,...

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Students are familiar with United States currency-dollar and cents. They are asked to compare it with currency of another country. Students explore currencies of various countries using the Internet, video, and hands-on activities. ...
