Expand on learners' understanding of quadratic-linear systems. Building on the graphic understanding developed in the previous lesson, pupils learn algebraic methods of solving the systems. 

How can matrices help us solve linear systems? Learners explore this question as they apply their understanding of transformation matrices to linear systems. They discover the inverse matrix and use it to solve the matrix equation...

Explore the graphs of functions and equations with a resource that teaches scholars how to graph functions as a set of input-output points. They learn how the graph of a function is the graph of its associated equation.

Try to find an estimate when the exact answer is not clear. Using the General Certificate of Secondary Education Math review resource, pupils learn how to find an estimate to a cubic equation. Class members use the trial-and-improvement...

Are the Arctic ice caps really melting out of existence? Junior climatologists examine the statistics of ice decline through four math-based lessons. Each activity incorporates data, climate information, and environmental impact into an...

Friction leads to movement, heat, and melting on such a small scale most people don't notice. A short simulation permits scholars to observe the reaction between atoms as they move together.  The simulation applies the concept of...

Students assess informal methods to solve real-world problems that utilize simple equations that involve one variable. They incorporate concrete objects to assist them in the solving of a variety of equations. The students are actively...

In this solving equations worksheet, 9th graders solve and complete 21 different problems that include solving various equations that contain a variable on both sides of the equal sign. Then, students write an equations and solve it,...

In this equations review instructional activity, students solve algebraic equations with one variable.  They use inverse operations to solve for the unknown.  Students translate word sentences to number sentences and then...

Students explore multi-step equations. In this pre-algebra/algebra I lesson plan, students use the TI-nspire computer algebra system to check the steps they used to solve multi-step equations and equations with variables on both sides.

In this solving literal equations worksheet, students solve 30 equations. Students solve each equation for a given variable, but do not solve for a number answer.

In this systems of equations instructional activity, students solve 13 systems of equations.  Students use elimination to solve three variable systems of equations.

In this division worksheet, students solve algebraic problems containing fractions. This one-page worksheet contains 11 problems. Answers are provided. This worksheet may be completed on-line or produced in printed form.

This worksheet offers six problems to practice solving simultaneous equations using the method of elimination. Start with systems that require multiplying only one of the equations. Then move to systems which require multiplying both...

A instructional activity that offers four problems to practice solving simultaneous equations by graphing. Equations are presented in slope-intercept form or standard form. Problems include two with unique solutions, one with no...

Use this equations worksheet to have your learners solve word problems containing equations with variables. They complete 10 multiple choice questions.

In this simplifying expressions learning exercise, pupils combine like terms and complete 18 different problems. 

Learners solve word problems and regular number problems having to do with equations with variables. They complete 10 problems.

Students, using algebraic operations, solve and check linear equations. At the beginning of class, they write a paragraph comparing the solving of math problems to solving real life problems. Students observe solving systems of two...

Graph polynomials and identify the end behavior of each polynomial function. The class differentiates between linear, quadratic, and other polynomial equations.

Math manipulatives are wonderful for demonstrating any number of mathematical concepts in a concrete and visual way. Learners review the addition property of equality and the zero property using a scale model kit (not shown). They...

Students make equations from everyday data. They create a graph from the equations. Students predict and analyze the results. Students complete the second scenario on their own and turn in their handout.

Middle schoolers explore grouping symbols to mathematical equations to discover the importance of the "order of operations." Learners compare the absence of commas in connected text to the absence of grouping symbols in mathematical...

Students create addition sentences. They review number lines and how to jump between numbers to solve equations. They play the "Magic Number" game by using a spreadsheet and guessing numbers. They discuss how they found the magic numbers.
