A guided-inquiry lesson asks seventh graders to research the compelling question, "What does it mean to be equal?" Guided by three supporting questions, researchers complete three formative performance tasks and gather evidence from...

Fifth graders explore equality and inequality by participating in a Tilt/Balance activity. The students listen to the story "Lemonade for Sale" by Stuart J. Murphy and use equations to graph lemonade sale profits.

You can't go wrong with a activity that involves candy! Learners solve and graph one-variable inequalities and use candy to graph the solution. Individuals associate open circle graphs with life savers and closed circle graphs with round...

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Young scholars investigate the Napoleon triangle theory. In this polygon lesson, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral triangles to...

When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

Not all triangles are created equal. A simple hands-on activity has learners investigate the side lengths of triangles. They use pipe cleaners to determine whether triangles of given side lengths can exist and then use the results to...

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...

Examine numbers in scientific notation as a comparison of size. The 14th lesson in the series asks learners to rewrite numbers as the same power of 10 in scientific notation to make comparisons. Pupils also learn how to use a calculator...

Students solve and graph inequalities on a number line. In this algebra instructional activity, students solve using addition, subtraction, multiplication and division and graph their solutions using open or closed circles. They graph...

Students graph and shade inequalities. In this algebra lesson, students graph inequalities using the slope-intercept form. They shade the side of the line that is the solution and identify the domain and range.

Students solve linear inequalities. In this algebra lesson, students rewrite inequalities using one and two step equations. They graph their findings and identify the slope and solution of the line.

Students solve equations representing exponential functions. In this algebra lesson, students interpret their equations by analyzing the slope and y intercept. They find the slope using the slope formula.

Students analyze and solve linear equations. In this algebra lesson, students solve inequalities using the slope and y intercept. They rewrite word problems into algebraic equations and solve for the unknown.

Welcome learners to the world of algebra. Use a lesson that poses a situation involving the profit from creating greeting cards to teach about algebra. It requires scholars to use linear functions and inequalities to solve problems.

Eighth graders study the ratification of the 14th Amendment and the Plessy v. Ferguson decision.  In this US History lesson, 8th graders read excerpts from the Brown v. Board of education decision.  Students investigate one of...

Students explore the history of the environmental justice movement. They examine how discrimination promotes environmental illness in low income communities. Students explain why minority and low income groups have less economic and...

Young historians envision what life was like for African Americans living in the Jim Crow South through hands-on, experiential activities. 

Students draw a chart (included in the instructional activity) to use with their investigation. They review terminology of triangles and receive toothpicks to use in the instructional activity. Beginning with three toothpicks, students...

The rides at a theme park always have limits on weight or number of riders. This makes a natural example of the use of inequalities to solve real-world problems. Learners explore intuitive solutions using substitution to solve the...

Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. In this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by...

Properties about triangles are explored in this lesson. Geometers make conjectures about the length of a triangle's sides, the length of the angles in relation to the length of the sides, and the measure of the exterior angles of a...

Tenth graders investigate the theorems of angles and lines to prove triagle sum theorem. In this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two...

Students become familiar with how to get information from the Internet. In this math and technology lesson plan, students measure objects on a measurement sheet found on a web site. They practice using a standard unit of measurement...
