Now that learners figured out how to solve for one variable, why not add another? The lesson demonstrates, through examples, how to solve a linear system using graphing, substitution, and elimination.

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

Combine your lessons on Venn diagrams, probability, and multiples with several activities. After picking seven cubes, learners note the number of cubes that are blue and mark them in a Venn diagram. The next assignments prompt them...

What are the three most important items for survival? Readers of Viktor Frankl's Man's Search for Meaning, ponder this question individually and share their list with a group, that must then reach consensus on the three most...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

You know the Inscribed Angle Theorem and you know about tangent lines; now let's consider them together! Learners first explore angle measures when one of the rays of the angle is a tangent to a circle. They then apply their...

So, you've just spotted an ad for the perfect job, now what? Get kids ready to enter the workforce by having them practice the first step, replying to a job ad. They scan the paper for a job, role-play responding to the ad via phone,...

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

Make a game out of solving equations. This particular activity works well for pairs of learners. Follow the instructions to have player one pick a number and player two verbally give an equation. Participants need to make sense of a...

Understanding how our calculus derivative formulas were derived, connects learners to the idea that the study of mathematics is continuous and cumulative. Learners will also develop a deeper appreciation for the short cuts used to find a...

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

As part of a study of Viktor Frankl's Man's Search for Meaning, class members respond to, and craft, higher-level comprehension questions based on passages from the text. 

Who knew that the Egyptian, Julian, and Gregorian year were different lengths? Your mathematicians will! They will have to calculate the difference between the years in seconds and find the percent change. Using dimensional analysis,...

This is a great idea for any social studies classroom to incorporate throughout the year as an ongoing project! Line your walls with a continuous strip of butcher paper to design a large timeline that you can add to as you cover...

Every writer knows how terrible writer's block can feel. Use these five writer's block-busting techniques to help young writers get out of their rut and into a better state of mind.

Learners identify their beliefs and values and compare how these values relate to those of their community. They then determine how their values affect the roles they play in different situations. A quiz about values and beliefs...

Have you ever been singled out in a crowd before? Pupils investigate and analyze the events of the Holocaust. They dive into the life of a middle school student, as well as the diary entries of those in Kristallnacht during World War...

How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Students are asked to divide the...

A hand-drawn thermometer provides a strong visual for how much of an emotion a child is feeling. Scholars color the thermometer's mercury to showcase whether what they are feeling is high or low at a certain moment. Questions allow...

This is a very simple PE game that can be performed indoors or outdoors, and will help your learners develop a sense of direction! If playing this game outdoors, identify north, south, east, and west, and consider varying the type of...

An informative video and handout provide the basic information needed to reflect any pre-image across either of the axes on the coordinate plane. The printed resource provides a preview of reflecting across lines other than an axis....

You know how to factor expressions; now it's time to go the opposite way. Scholars learn to write algebraic expressions in expanded form using the distributive property. A problem set helps them practice the skill.
