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.
Expressions, Equations, and Functions
Here is an unexpected resource: chapter 1 of an Algebra textbook. You can use all or some of its contents to teach your Middle Schoolers all about algebraic expression, domain, function notation, linear equations, order of operations, input/output, ordered pairs, and variable expressions. This would be great for a substitute or newer teacher looking for reliable tools.
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.
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.
Opening a Business
An algebraic expression is a combination of number(s), variable(s), and one or more operations. Use these real-world scenarios to introduce writing verbal phrases as algebraic expressions. Small groups of learners are opening up a business and must figure out how to manage their money in one of three scenarios: 1) Creative Cupcakes 'N More 2) Books, Movies, and Games Galore 3) Sporting Goods Fanatics. They need to come up with a plan and be able to support their plan.
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.
Grade 7 Patterning and Algebra: Algebraic Expressions
Classmates solve 18 different problems that are mostly word problems that apply algebraic expressions. They draw different combinations of masses on a scale that would balance. They also simplify expressions and solve for x in a number of equations. In addition, they write a mathematical expression to describe each situation presented. A link to a math game, colorful graphics, and word problems make this a well-rounded resource.
Translating Between Verbal and Algebraic Expressions
Students translate between verbal and algebraic expressions. After folding paper into four sections (multiplication, division, addition, and subtraction), students list code words under the appropriate section title. Next, they participate in a "I Have, Who Has" activity where the students practice matching an algebraic expression to a verbal expression.
Introduction to Variables and Algebraic Expressions
Begin your next algebra unit with this introductory lesson on variables and algebraic expressions. This plan requires a SMART board and includes a SMART notebook file. The file contains a guiding question and two learning activities that will teach learners to write simple algebraic expressions using a single variable.
Interpreting Algebraic Expressions
Interpreting algebraic expressions is a fundamental skill in beginning algebra. This lesson approaches the task in numerous ways. First, learners assess their understanding with a short worksheet on converting between words and expressions. They then work in pairs to translate between words, symbols, tables of values, and graphic area representations of expressions. Using card sets to match representations keeps them engaged. All or part of this well-written lesson could be used to evaluate, or extend your young scholars' understanding.
Factorizing Algebraic Expressions
In this comprehensive learning exercise, mathematicians solve and complete various types of problems on factoring and using the quadratic formula. This learning exercise also includes the use of factoring to simplify rational expressions. Overall, it provides a good review or study guide.
Algebra...Your Second Language
Help learners translate word problems into algebraic equations. They will rewrite words using symbols and evaluate algebraic expressions using real life scenarios, animation sequences, video presentations, and activities to help students engage in learning. Activity pages are included.
Write Algebraic Expressions Using Multiplication and Division
Go beyond adding and subtracting and write an algebraic expression with multiplication and division. Learners can plug different numbers in for the variable by using a table to organize answers. Use with previous instructional activity for expressions with addition/subtration or with later videos for multi-step expressions. Video is third in a five-part series.
Determine Whether an Algebraic Expression Matches a Scenario
Sometimes learners find an answer and pick the first one that matches. This video shows that an algebraic expression can be written in different ways that are still correct. Learners can interpret a scenario into an expression and see which answer choice it matches by evaluating. Use with previous videos for practice on writing simple and multi-step expressions. Video is the last in a five-part series.
Write Algebraic Expressions Using Addition and Subtraction
Get started with the language of math by writing algebraic expressions. Your learners can practice interpreting different scenarios into expressions using addition and subtraction. Have them plug in different numbers for the variable and use a table to organize answers. Use with the next videos in series for practice writing expressions with multiplication and division. Video is second in a series of five.
