Students examine the need for a national library. In this Library of Congress lesson, students analyze primary sources to investigate the persuasive techniques that Thomas Jefferson used in a letter meant to show his...

Students investigate glaciers. In this earth science lesson plan, students use sandy ice cubes to observe how glaciers change the land. Students list forces that cause changes in the Earth's surface.

For this commutative and associative property worksheet, students simplify 12 problems. Students then name the property illustrated in 4 problems.

Eighth graders engage in a lesson that is concerned with the properties associated with 8th grade Algebra. They solve problems using a variety of contexts and participate in using real world problems to create context. Students...

Students observe and complete various math problems involving the commutative and associative properties of multiplication. They observe the teacher solve examples of each property, and complete two worksheets.

In this polynomials worksheet, 9th graders solve and complete 17 different problems that include adding and subtracting various polynomials. First, they determine the sum or difference of each equation listed, combining like terms when...

Students study the commutative and associative properties. In this multiplication lesson, students review the properties and solve several multiplication problems.

In this algebra worksheet, students identify and use the properties of real numbers to solve problems. They identify and differentiate between rational and irrational functions. There are 13 problems.

Scholars are introduced to the usage of the Order of Operations. They explore the use of variables and how they are represented by any letter of the alphabet. They then engage in discussion for verbal assessment.

Students explore multiplying polynomials. They observe solving polynomials using the standard order of operations, FOIL, and the box method. Throughout the demonstration, students explore strategies of solving word problems such as...

Looking for a learning exercise on special products of binomials? This one-page document includes two separate assignments on special products. Problems include multiplying binomials in the form (a+b)^2,(a-b)^2,(a + b)(a -b), as well as...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...

Young mathematicians solve linear equations by drawing models of algebra tiles using colored pencils. To finish, they solve the same equations algebraically and check their answers using a graphing calculator.

Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

Do properties of equations hold true for inequalities? Teach solving inequalities through the theme of properties. Your class discovers that the multiplication property of equality doesn't hold true for inequalities when multiplying by a...

These equations are missing numbers, and scholars must process multiple operations to complete them. There are addition, multiplication, and division problems here, each missing an addend, divisor, or factor. After completing 24 of these...

Make two parts into a whole. Scholars learn to multiply polynomials to create a simplified polynomial expression. Polynomials include monomial, binomials, and trinomials. 

Express your love of equations! Pupils first learn to write and simplify numerical and algebraic expressions. Then, create and solve two-step equations. The progression is a great way to introduce the concept slowly.

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

Something for young mathematicians to remember: the sum of any two sides must be greater than the third. Class members investigates the Triangle Inequality Theorem to find the relationship between the sides of a triangle. At the...

Communication is the key. A dozen sample items require scholars to communicate their reasoning involved in arriving at a solution. The PowerPoint from the Gr. 8 Claim 2 - 4 Item Slide Shows series uses a variety of content to...

A woman accuses her husband of multiple instances of domestic violence in the mock trial case, Karmia Kahn v. Keith Kahn
