Lesson Plan Template __Title__: Translating Algebraic Expressions Date: __Grade Level(s)__: 7, 8 __Related Standards__: 6.A.1, 6.A.3, 7.A.1 Performance Indicators: 6.A.3: Students translate two-step verbal sentences into algebraic expressions. 7.A.1: Students translate two-step verbal expressions into algebraic expressions. __Description__: Students will be able to translate two-step verbal expressions into algebraic expressions. __Duration__: 90 minutes ( 2 days – 45 minutes each day) __Learning Objectives__: Students will be able to translate two-step verbal expressions into algebraic expressions. __Vocabulary:__ variable, algebraic expression, phrase, equation open sentence __Materials__: Impact Textbook Closing Activity: Matching Verbal and Symbolic Expressions http://www.quia.com/mc/319817.html __Support Materials__: > __Step by Step Procedure__: Problem of the Day Have students complete the Expression/Equation Vortex, using the SMART Board. The purpose of this activity is to see if the students can recall the difference between an expression and an equation. Mini-Lesson (15 minutes)  a) 7 more than 9 times a number, n 7 + 9n b) 5 minus the product of a number, v, and 3 5 - 3v c) 15 increased by th quotient of 60 and a number, w 15 + 60/w d) 9 less than the product of 37 and a number, j 37j - 9 A) A number v, divided by 8. B) the sum of a number g, and 18. C) the difference of a number, u and 10. D) three times a number, x.  Small Group (15 minutes) a) four plus three times a number ,t b) seven plus twice a number, r  c) the product of fourteen and a number, y, decreased by 5  d) ten less than the quotient of a number, g, and 3 Independent Practice (5 minutes) Pink Workbook page 48 all Homework Coach Book page 54-55 ex 1-11 Lesson Quiz/Closure (10 minutes) __Submitted By__: Frances Samuel
 * variable: a letter that represents an unknown quantity that can change or vary.
 * algebraic expression: a rule written with numbers and symbols.
 * SMART board activity: Expression/ Equation Vortex
 * SMART Board File: [[file:Writing Expressions.notebook]]
 * Begin by reviewing the problem of the day. Refer to Pink Skills workbook page 47 for key operation vocabulary for expression. For example: addition keywords include sum, plus, more than, increase, etc. Subtraction keywords include: difference, decreased by, less than, differs from, etc. **//See the table below for complete keyword vocabulary.//**
 * Work with students to match each verbal expression to its algebraic (symbolic) expression:
 * Have students write an algebraic expression for each of the following expressions.
 * Have students complete the following problem is small groups.
 * Have students write two algebraic phrases. Make sure they incorporate the language from the table during the mini-lesson. They will exchange their phrases with a classmate who will write the algebraic expression for each.
 * Have students complete the Quia Game that is included in the SMART Board Lesson.
