This product, Express Yourself — Part 2: If the phrasing indicates addition, place a plus sign between the designated variables and constants. The fourth product, Express Yourself - Part 4: Writing Expressions from Phrases: Writing Expressions, takes the students one step further by switching the focus to how to write and use algebraic expressions from word phrases and then to solve word problems.
How to Write an Algebra Expression By Amy Harris; Updated April 24, In order to write algebraic expressions successfully, you must have some familiarity with fundamental algebraic operations and key terms.
This product is the second of four products which focus on the wonderful world of algebraic expressions. This product, Express Yourself - Part 2: The worksheet asks the students to write a myriad of algebraic expressions of increasing difficulty, and the puzzle solidifies these concepts even further.
Before students begin to write expressions, they must understand a few properties, such as the Commutative Property, so that they know, for instance, in what order to write the terms in a given expression.
You may choose any letter of the alphabet. The third product, Express Yourself - Part 3: For instance, you must know the significance of a variable, which is a letter that acts as a placeholder for an unknown number. Includes a warm-up activity, two-pages of guided notes, and two two-page word problem worksheets.
If the phrasing indicates division, create a fraction with the variable and indicated number. Simplifying Expressionsfocuses on simplifying expressions, manipulating variables algebraically using various number properties including the distributive property. The guided notes allow the teacher to walk the students through a step-by-step process for how to set up expressions for word problems and evaluate them for given values.
The warm-up activity reviews evaluating expressions and writing expressions for phrases and begins to explore word problems. These activities introduce the Commutative, Associative, and Identity Properties in a quick and creative way. Determine whether the problem involves a multiplication or division operation.
The first product, Express Yourself - Part 1: Tip You may interchange the order of variables and constants for addition.
Using mathematical properties and order of operations correctly are emphasized throughout these activities.
Includes an introductory activity and a two-page discovery worksheet. They take the students to the final level of writing expressions, asking them to write and then evaluate simple to complex algebraic expressions involving one, two, or three operations.
Writing and Evaluating Expressions for Word Problems: Write Algebraic Expressions Choose a letter to use as the variable. Expressions can consist of variables, constants and operating symbols such as plus or minus signs.
As mentioned above, this product is ideally used immediately after using Express Yourself - Part 1: If the phrasing indicates multiplication, place the variable you selected directly on the right of the designated number. Write it in lowercase text. In this case, reverse the order.
The word problem worksheets are complete with pictures and problem types that range from money to cookies to cats to Sumo Wrestling to geometry to converting between types of temperature. This begins the process of readying them for a future Algebra 1 course. Do it with the students as often as necessary to keep that enthusiasm going!
Review and Unit Testis a comprehensive review and unit assessment for the concepts learned and taught in the first three. However, expressions never contain equals signs -- adding an equal sign to an expression would turn it into an equation.
Feel free to also check out a growing number of other products that use poetry, songs, games, worksheets, and assessments to make math fun and help students to learn a variety of common core math standards.
