Solving First Degree, Single Variable Algebraic Expressions
Middle schoolers will identify the parts of an algebraic expression by telling the number of terms in one expression. Then they will collect like terms and solve three problems. Next, they will complete a table involving three sets of algebra tile displays, evaluating each with a given value of x. In all they will solve 4 application problems. Answer key is not included.
Concepts In Advanced Algebra
Students investigate the achievements of the Chinese in mathematics. For this algebra lesson, students convert Chinese number and decimal numbers and solve a 3x3 systems of equation. They relate art to mathematics also.
New! Evaluate Multiple Step Algebraic Expressions by Substitution
This easy-to-understand video demonstrates how to find the value of multi-step algebraic expressions with substitution. It reviews order of operations to help learners avoid common mistakes when solving. The sample problems show all four operations and use different values for substitution. As an added bonus, the resource includes a Spanish version of the video.
How Do You Plug Variables into an Algebraic Expression?
The instructor demonstrates how to plug-in given variables to rewrite an algebraic expression as a numerical expression. Follow the order of operation rules to simplify the numerical expression once you have plugged in those given values.
Building Bridges to Algebraic Thinking
Students attempt to make a transition from arithmetical to algebraic thinking by extending from problems that have single-solution responses. Values organized into tables and graphs are used to move toward symbolic representations.
Working with Algebraic Expressions
Learners understand that algebra is a branch of mathematics that uses symbols or letters to represent unknown numbers in problems. They also understand the definition for an algebraic expression. Make sure to click on the Download the Activity bear so that you can access a top-notch task document that walks learners through the evaluation of algebraic expressions. It can be used as part of your lesson or sent home as reinforcement.
Can We Handle the Truth? How are a Truth Table, a Logic Circuit and Boolean Algebra Related?
How does algebra relate to real life? High schoolers will construct and test computer chips to determine the function of each, and discuss real life applications of the Boolean Algebraic concept. Included are discussion questions, gender equity considerations, web links, a clear procedure, and all necessary worksheets. The format is a slide show.
Intermediate Algebra Practice Problems
In this algebra practice worksheet, 6th graders solve various equations, graph solutions and functions, evaluate logarithmic forms, find unknown equations, write formulas and expanded form, use the binomial theorem, etc. Students solve 36 problems.
Renting Cars, Stealing Money, and Linear Functions
When comparing pricing models, young mathematical consumers, create linear equations and analyzing them graphically and algebraically. They look at the meaning of slope and intercepts, as well as the intersection points of lines.
Young scholars study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Young scholars also graph the data they collect and describe using an algebraic formula that gives the age of an object as a function.
Ratio Problem With Basic Algebra (new HD)
Sal solves ration problems where he compares ratios and uses algebra to find unknown ratios.
Picture Frames and Algebra
Middle schoolers create a method for finding the area of a fame for a picture and then transfer their shared methods into algebraic expressions. They develop the algebraic language to communicate and solve problems effectively and use variables and symbols to write equations. Pupils use the computer to examine graphic representation of their equations.
Picture Frames and Algebra
Students evaluate the area of a picture frame and write algebraic representations. In this algebra lesson, students work in groups to find the area of different picture frames. Students then write algebraic expressions and present then to the class.
Completing the Square Using Algebra Tiles
Challenge your class to complete word problems using algebra tiles about completing the square. Students complete 16 problems. Note: The answer key is not included.
Get Lucky and Algebra Jeopardy
Students manipulate integers quickly to get their answers. In this algebra lesson, students play an interactive game as they review basic algebraic operations. They add, subtract, multiply and divide quickly to get the correct answer.
New! Evaluate One-Step Algebraic Expressions by Substitution
How do algebra learners know the value of an algebraic expression that contains a variable? This video shows your number crunchers how to evaluate an algebraic expression by substituting a given number for the variable. In fact, it models an algebraic expression where the value of the variable changes and demonstrates how this changes the value of the expression. The video is part of a series on reading, writing, and evaluating algebraic expressions.
New! Use Alternative Notation for Multiplication and Division in Algebraic Expressions
Using the letter x as a variable and to represent multiplication can be confusing to algebra learners. Present newcomers with the alternative notation for multiplication and division modeled in the video. After showing the video, try out the included Guided Practice, which asks learners to rewrite written algebraic phrases as algebraic expressions. An effective standalone video that is the second in a series on writing, reading, and evaluating expressions.
New! Read and Write an Algebraic Expression Containing a Variable
How do you write five less than a number as a mathematical expression? Show algebra learners how to read and write algebraic expressions by using variables with this introductory video. The first in a series, the video models how to translate the unknown into a variable and how to recognize clue words that indicate what operation to use. Challenge your class to rewrite algebraic expressions in word form with the extension activity found at the end of the provided Slides.
New! Read and Write Algebraic Expressions Using Parentheses
How does an algebra learner know what to put in parentheses when writing an algebraic expression? This video, which models how to use parentheses, begins by directing viewers to find the comma in the written algebraic phrase. The comma tells learners that everything before it is a separate expression and is to be done first. In the order of operations, parentheses always come first. The activity is part of a video series on how to write, read, and evaluate expressions.
New! Evaluate Algebraic Expressions with Exponents
Show your learners that exponents are important in the order of operations. The video presents a useful method for evaluating an algebraic expression with exponents and attempts to eliminate the common mistake of multiplying the exponent and base. The provided Slides include a guided practice problem, extension problems for more advanced pupils, and a short quiz. The video is part of a series on how to write, read, and evaluate algebraic expressions.
