This all-encompassing lesson plan immerses your math class in the world of algebraic expressions. Written details are provided to guide you in guiding them to identify the parts of an expression and simplify them. Sample problems are provided for learners to practice with, including real-world applications. An answer key follows the worksheet.
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.
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. 
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.
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.
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.
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.  
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.
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.
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.
Sixth and seventh graders explore the concept of simplifying algebraic expressions. They review the order of operations and apply properties to simplify and compare them. The author suggests using a "Boxes Game" as a motivator to get teams practicing the new skills. The lesson is not exciting, but it does serve its purpose. 
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.
Examine algebra using digital resources! Budding mathematicians will watch Cyberchase episode segments that propose a problem. Using information gathered from the video, they practice recording number patterns in several different ways: two-column tables, line graphs, and simple algebraic equations. Note: Links are included.
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 lesson for expressions with addition/subtration or with later videos for multi-step expressions. Video is third in a five-part series. 
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. 
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. 
Put all the operations together and write one multi-step algebraic expression. Your learners will examine different parts of a scenario and recognize which operations to use. Have them write out the expression and evaluate with three different inputs. Use with prior videos for practice writing simple algebraic expressions or next video for real-world example. Video is fourth in of a five-part series. 
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.
Show your learners how to regroup algebraic expressions with visual support. The video demonstrates how to take larger groups of items and break them into smaller groups using the distributive property. Similar to factoring, use this video along with the previous video for more visual examples of grouping. Note: This is the sixth video in a series of seven
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.
