Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Second graders use a number line to practice subtraction.  For this subtraction lesson, 2nd graders use a number line to count backwards.  Students participate in mad math activities and solve problems.

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.

Learners 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. Learners represent the correct...

High schoolers use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.

Students investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and debits.

Sixth graders use their knowledge of algebraic expressions and equations to write expressions and equations.

During this lesson, the young scholars will use growing patterns to develop an algebraic expression with understanding. The students will also learn mathematical vocabulary with the use of the newly created expression.

Sixth graders use their knowledge of algebraic expressions and equations to write expressions and equations using appropriate math symbols.

This Algebra lesson focuses on writing algebraic expressions to represent real-world problems, using the properties of numbers to simplify expressions, and evaluating equations by isolating the variable.

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...

This lesson offers a list of 17 downloadable tasks for high school algebra students to practice interpreting expressions that represent a quantity in terms of its context. Interpret parts of an expression, such as terms, factors, and...

The students will extend the knowledge of algebraic expressions from geometric representations and ultimately graph linear equations with understanding. The students will also develop a better understanding of algebraic expressions by...

This task presents a challenging exercise in both algebraic manipulations and seeing structure in algebraic expressions. Aligns with A-SSE.B.3.a and A-SSE.A.2.

Young scholars will learn about translating between verbal and algebraic expressions via game play and possibly working on an interactive web site. The four steps to explicit instruction (I do, we do, y'all do, and you do) are labeled in...

This problem allows young scholars to see words that can describe the expression from part (c) of "5.OA Watch out for Parentheses." Additionally, the words (add, sum) and (product, multiply) are all strategically used so that the student...

Writing expressions paves the path to writing and solving equations.

Standard 5.OA.2 asks students to "Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them." This task asks students to exercise both of these complementary skills,...

This task challenges students to use rules to calculate and compare the cost of memberships.

This instructional activity provides learners 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...

The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation. Aligns with 5.OA.A.1.

Students build bridges and test their strength to collect data and write an equation. The concept of slope is explored in this activity.

Students use weight to collect data and investigate the linear relationship. This activity uses a graphing calculator.

The purpose of this task is to introduce the idea of exponential growth and then connect that growth to expressions involving exponents. It illustrates well how fast exponential expressions grow. Students who are just learning about...
