After completing this tutorial, you'll know what a linear equation is and how to solve one using various arithmetic properties. Contains several definitions, problems with step-by-step solutions, and practice exercises. Includes links to...

Eighth graders are presented with five linear equations with one variable and are asked to state whether they have a positive solution, a negative solution, a zero solution, or no solution. Aligns with 8.EE.C.7.

[Free Registration/Login may be required to access all resource tools.] Learn how to solve one-step inequalities using multiplication and division. Students watch videos, examine guided notes and attempt practice problems in order to...

Construct an equation or an inequality that models a given context. Modeling expressions can be quadratic, rational, or exponential. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video,...

This is an exercise in creating equations from a situation with many variables. By giving three different scenarios, students will be reviewing their definitions of the variables to emphasize the importance of defining variables when...

After solving one system of equations by the methods of graphing, elimination using addition or subtraction, elimination using multiplication, and substitution, learners will be given four systems to be solved by one of each of the four...

In this exercise, students will use inverse operations to solve the equations for the unknown variable, or for the designated variable if there is more than one. Aligns with A-CED.A.4.

In this young scholars are asked to write an equation to solve a real-world problem. There are two natural approaches to this task. In the first approach, students have to notice that even though there is one variable, namely the number...

In this instructional task students are given two inequalities, one as a formula and one in words, and a set of possible solutions. They have to decide which of the given numbers actually solve the inequalities. There are two solutions...

A type of pasta is made of a blend of quinoa and corn. The pasta company is not disclosing the percentage of each ingredient in the blend but we know that the quinoa in the blend contains 16.2% protein, and the corn in the blend contains...

This task has two separate goals: the first is to solve a pair of equations, one quadratic and the other linear. The second goal is to observe that a point that lies on a circle gives rise to a Pythagorean triple. Aligns with A-REI.C.7.

For this problem, students must determine how much quinoa and how much corn are in a type of pasta. They must study the ingredient list which shows the protein content of the pasta. They know that quinoa has more protein than corn and...
