Solutions of a Linear Equation
Use the distributive property to solve equations. The sixth lesson in a 33-part series has scholars solve equations that need to be transformed into simpler equations first. Class members apply the distributive property to the equations...

Valid Equalities?
True or false: 20 = 10 + 10. The statement is true because two 10s make a 20. These are the types of equations learners must label or false. They must also explain in mathematical terms how they know.

Mid-Module Assessment Task: Grade 7 Mathematics Module 3
Lesson 16 in the series of 28 is a mid-module assessment. Learners simplify expressions, write and solve equations, and write and solve inequalities. Most questions begin as word problems adding a critical thinking component to the...

Building an Explicit Quadratic Function by Composition
Use equivalent expressions to reveal information about their graphs. Pupils verify that two quadratic functions are equivalent. By comparing the two expressions, they determine the vertex, the zeros, the y-intercept, and the direction it...

The Defining Equation of a Line
They appear to be different, yet they are the same line. Part 24 out of 33 lessons provides a theorem about the relationships of coefficients of equivalent linear equations. Pupils use the theorem to determine whether two equations are...
Mathematics Assessment Project
Sorting Equations and Identities
Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.
Pearson
End of Year Practice Test (Grade 8 Math)
This is a great resource to keep daily material aligned to standardized assessments. It offers complete multiple choice and short-answer practice with a wealth of opportunities for customization. Offer it as a whole, to track progress or...

Sammy's Chipmunk and Squirrel Observations
Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns. Scholars could find the answer algebraically or create a table to analyze the problem in...

6.EE.4 Equivalent Expressions
Straight to the point, learners are asked to compare a set of five expressions, determine which are equivalent, and then write equivalent equations for those that do not have any. A benefit is that they will review using properties of...
Curated OER
Logarithmic Equations
In this logarithmic equations worksheet, learners cut apart 16 squares. Each square has four equations, one per side. They match equivalent equations, creating a new square when successful.
Curated OER
Equivalent Equations
Answer the age-old question every middle schooler has, what are equivalent equations? Here, they will explore the concept, discuss what equivalent equations are, and how to solve them. They also discuss performing an operation on both...

Introduction To Solving Equations
Use manipulatives (film cans and balance scales) to visualize and solve equivalent equations with your math class. After a lecture/demo, they utilize handouts and solve various equations using the methods learned.
