Give the class a mental work out with an assessment task in which young mathematicians compare several gym membership options. They use substitution to calculate the cost for given numbers of months.

Substitution is still the method of choice to verify number sentences. The detailed lesson has young mathematicians determining conditions for when number sentences are true or false through substitution. They learn to express these...

True or false? Scholars determine the truth value of equations and inequalities through substitution. All values to use for substitution are given with each equation or inequality. This is the 24th lesson in a module of 36.

Here is a resource where algebra learners show their understanding of a system of equations involving a circle and a line. Once graphed, learners see two points of intersection, one where the ordered pair is read, and a second where...

As if solving equations with an x isn't tricky enough, now they add a y, too? A pre-assessment gauges the knowledge of your classes related to systems. They are asked to solve graphically and algebraically and to solve word...

Knowing more strategies is always a plus. Pupils watch an engaging video to learn additional ways to algebraically determine the limit of a function at a specified value. The video covers multiplying radical expressions by their...

Teach about properties properly. Individuals investigate the commutative and identity properties for both addition and multiplication. They see that the properties hold true for all values by using substitution to test out several examples.

Learners explore the concept of solving systems of equations with two equations and two unknowns. For this solving systems of equations lesson, they work through problems of solving systems by substitution, elimination, and graphing....

Middle and high schoolers solve and complete 15 various types of problems that include evaluating expressions and graphing. First, they use the substitution method to solve pairs of equations for a variable. Then, students write out a...

Students differentiate the types of cryptosystems and use them to communicate privately. In this algebra lesson plan, students use substitution and transposition to identify the cryptographs. They send and receive cryptograms as...

In this linear systems worksheet, students solve systems of equations using three different methods: substitution, adding and subtracting, and graphing. This two-page worksheet contains three multi-step problems.

In this systems of equations worksheet, students solve ten sets of problems by using the substitution method. They first decide which variable they are going to solve for, x or y. Then, students replace that value with the other equation...

Students rewrite word problems using the correct symbols. For this algebra lesson, students simplify algebraic expressions and use the correct representation of the unknown. They solve equations using one and two steps operation.

In this algebra worksheet, learners solve systems of equations.  They evaluate matrix problems and identify the determinant.  This two-page worksheet contains 13 problems.

In this algebra lesson, students solve systems of equations. They solve using substitution and elimination. There are 10 questions.

For this solving systems of equations worksheet, 9th graders solve and complete 12 different problems algebraically. First, they solve each system of equations using substitution. Then, students solve each system of equations using...

Students practice solving systems of linear equations using the substitution and elimination methods. They determine if the system has one, infinite or no solution. Students also graph the linear equations.

In this verifying segment relationships worksheet, 10th graders solve two proofs by following the same format used in algebra. They complete each of two proofs by naming the property that justifies each statement given. Students also...

In this algebra worksheet, 11th graders solve 14 systems of equations using substitution or elimination and 14 word problems.

In this variable expression worksheet, students substitute values for given variables and simplify the equation. This one-page worksheet contains ten problems.

In this algebraic equations learning exercise, students solve and check ten algebraic equations. In the first 3 problems, they find the solution of the equation by using the substitution method. And in the last 7, students solve for each...

Students solve systems of equations algebraically. In this algebra lesson, students solve systems using substitution and elimination. They solve linear and quadratic systems.

Seventh graders, in an introductory algebra class, code and decode messages using substitution ciphers. Role-playing as mathematicians, they work in groups to decipher several messages, one of which translates to "math is awesome."

In this substituting numbers worksheet, students solve 30 problems in which numbers are substituted into algebraic expressions. This page is intended as an online activity, but may be completed on paper.
