Search form Search Problem: Jensen likes to divide her class into groups of 2. Use mathematical symbols to represent all the students in her class. Let g represent the number of groups in Ms. In the problem above, the variable g represents the number of groups in Ms. The value of this number can vary change.

Let's look at an example in which we use a variable. Write each phrase as a mathematical expression. If x is 6, then the expression has a value of In the next few examples, we will be working solely with algebraic expressions.

Write each phrase as an algebraic expression. Write each phrase as an algebraic expression using the variable n. How much money will each employee get? The amount of money each employee will get is represented by the following algebraic expression: Write an algebraic expression to represent his earnings for one day.

Let x represent the number of hours the electrician works in one day. The electrician's earnings can be represented by the following algebraic expression: The value of this number can change.

The value of this expression can change. Choose the algebraic expression that correctly represents the phrase provided.

Write the algebraic expressions from the sentences. These pre algebra worksheets have the answers on the 2nd page of the PDF. Read the sentences and determine how to write the algebraic expression or equations. Understanding how to write algebraic expressions and equations is a prerequisite for learning algebra. Students write the value of each expression when x = 2. 3x + 7 13 4x + 8x 24 x + 2x + 3x + 4x 20 x ∗ 2x - 9 -1 6 + x - (_1 2)x 7-(2x) - (-9) 5 1 Teaching the Lesson Math Message Follow-Up WHOLE-CLASS DISCUSSION Algebraic Thinking Draw two name-collection boxes on the board, one for each expression. Record students’ answers in the name-collection boxes. Memorize the most common words for each operation. Always look for "turn around" and (parenthesis) words. When writing an expression for a word problem use variables that are representative of the problem. For example, lett h represent hours.

Select your answer by clicking on its button. If you make a mistake, choose a different button. Fifteen less than twice a number.Grade 6 Mathematics Module 4.

Students read, write and evaluate expressions in order to develop and evaluate formulas. From there, they move to the study of true and false number sentences, where students conclude that solving an equation is the process of determining the number(s) that, when substituted for the variable, result in a true.

Writing multi-part algebraic expressions Some expressions are slightly more complicated than the ones we looked at on the last page.

For instance, some expressions . Algebraic expressions – a key stepping stone toward a complete understanding of algebra.
