Continue with this activity until you are certain that the students are understanding the work and making progress connecting the idea of verbal phrases and algebraic expressions being representative of one another.
Choose the algebraic expression that correctly represents the phrase provided. Search form Search Problem: Make sure you are circulating actively, going to each group multiple times, making sure that they are making the connection between the expression and the written phrase they are creating.
Since this is predominantly a knowledge skill, coded as K in the Florida Standards, the assessment for this lesson is going to have the students directly demonstrate their knowledge.
Ask the students to give you as many clue words as they can think of that tell them what operation to use in a problem. Students will be able to: For students who are are unable to work at the same pace as other students, modify the summative assessment to odds only, evens only, or a combination of the problems that you want to see them solve.
Reload the game they played a moment ago. What prior knowledge should students have for this lesson? The value of this expression can change. If you make a mistake, choose a different button.
How much money will each employee get? General Lesson Plan Learning Objectives: Students should know basic clue words for different operations, such as sum, difference, quotient, product, etc. To ensure that students understand the relationship between phrases and algebraic expressions, they will now work backward from the expression to phrase.
Students are to work with their partners to write a phrase that goes with each of the four expressions. Have them copy the expressions from their summative assessment onto a piece of paper, place an equals sign at the end of each expression, assign each one a value, and then solve for the variable.
This should be addressed both as part of the lesson and also while circulating. What activities or exercises will the students complete with teacher guidance? The Game consists of 11 multiple choice questions. In the next few examples, we will be working solely with algebraic expressions.
For students who struggle with the clue words, allow them to sit directly in front of the chart paper you created covering the operations and their clue words. If you replaced the variable with different numbers and solved, does the expression you wrote make sense?
Use mathematical symbols to represent all the students in her class. If you have Clickers, the class can compete against you as a whole.
For students who grasp the concept of expressions and phrases quickly, challenge them to turn their expressions into equations. In the problem above, the variable g represents the number of groups in Ms.
Tell the students that they are going to be playing a game at the beginning and end of class. They will be analyzing phrases and deciding which expression represents that phrase.
Please login at the top of this page to access this resource. Attend to Precision since students must precisely match expressions with the verbal situation. Jensen likes to divide her class into groups of 2.
The amount of money each employee will get is represented by the following algebraic expression: The students will write 4 - c when the correct answer should be c - 4. This resource requires special permission and only certain users have access to it at this time.
Zoom in your LCD projector or your desktop screen so that the phrase does not show, only the multiple choice expressions. Feedback to Students Common Error: What should students know and be able to do as a result of this lesson?Create free worksheets for writing simple expressions with variables (pre-algebra / algebra 1 / gradeseither as PDF or html files.
The problems give the student the expression in words, such as the quotient of 7t and 5, the difference of x and 8, divided by 2, or the quantity 8 plus 2t, cubed, and ask the student to write a mathematical expression to. The worksheets in this page provide practice to students on translating phrases into algebraic expressions like linear expressions, single & multiple variable expressions, equations and inequalities.
This will help the students to translate real-life problems into algebraic expressions and find a solution in an easier way. Writing and Evaluating Expressions Worksheet Evaluate each expression using the values m = 7, r = 8, and t = 2.

These Algebraic Expressions Worksheets are a good resource for students in the 5th Grade through the 8th Grade. To write algebraic expressions and equations, assign a variable to represent the unknown number. In the table below, the letter “x” is used to represent the unknown.
In translation problems, the words sum, total, difference, product and quotient imply at least two parts – use parentheses when a sum or difference is multiplied. The most important part of writing expressions is to know that words for addition, subtraction, multiplication and division.
It is also important to know "turn around" words and words that indicate the use of parenthesis.Download
