Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.

Fifth graders determine which container made from a single sheet of paper has the greatest volume. They look the solutions made by three different students before working on their own examples.

Students, after reading an explanation from a NASA Web site, demonstrate an understanding of the text by applying it to questions involving the Thrust to Weight Ratio and Excess Thrust of an aircraft.

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Students complete a variety of bear-related activities. They sort and graph teddy bears, distinguish between real and non-real bears and research bear life cycles and habitats.

Young scholars work with dominoes to recognize the number of spots on each side as they relate to addition facts. In this seeing doubles lesson, students make triangle shaped flash cards for the double facts. Young scholars represent the...

Sixth graders work with the concept of equality and balance to solve one and two-step algebraic equations.

This lesson provides students with opportunities to practice writing equivalent equations and expressions for finding perimeter and patterns on a calendar. It also gives extension and remediation ideas as well as related instructional...

Use real world examples to evaluate and solve expressions.

This multi-segment lesson plan uses games and calculators to explore the concept of equivalent expressions. Students work together using inverse operations to isolate variables in algebraic equations. It also provides attachments for...

Writing expressions paves the path to writing and solving equations.

A comprehensive lesson on algebraic thinking where learners create and identify patterns using proportional reasoning. Research based, this lesson includes technology connections, items for discussion, and extension activities.

This lesson plan will result in students solving equations and using properties to form equivalent expressions. It provides downloadable PDF resources to go along with the instructional activity as well as strategies for diverse...

Sixth graders love working in stations to solve numerical expressions!

SWBAT to use the orders of operations to solve numerical expressions.

Is it any wonder that learners are suspicious? We lead, sometimes drag, them through Algebra I insisting they must follow the order of operations. We make them learn the "hard way" of doing an assignment one day only to show them the...

This lesson is designed to review and reinforce three methods (graphing, substitution and elimination) of solving systems of linear equations. The students will work together and independently to find the solutions to systems of...

This lesson provides young scholars with a real-life application of problem solving. Students will use color counters to model writing expressions and equations. They are given a scenario to follow where clues about the content of bags...

This problem can be solved using simple arithmetical reasoning but is also naturally represented by a simple equation. Thus, it provides a good entry point for students into representing quantities in contexts with variables and...

The goal of this lesson is for middle schoolers to use manipulatives to add integers, creating concepts rather than memorizing rules. This lesson will be related to the 300 Spartans who battled the invading Persians at the Battle of...

Using decks of cards and knowledge of number operations, students develop multi-step equations to reach a target number.
