9 Mathematically Speaking! Write your name and your partner s name. Person #1 explains how to solve the first problem to person #. Person # should mark a tally mark on the chart each time a vocabulary word is used. Encourage your partner to keep on talking until he or she has used all the target words. Then person # should explain how to solve the second problem while #1 marks on the chart. Mathematics Vocabulary coefficient discriminant formula identify opposite quadratic radical roots second degree polynomial square root standard form substitute #1 # What did you notice about the explanations?

10 Algebra Support Topic: Graphing Quadratic Functions Quadratic Functions Graph Match Activity Teacher Instructions: Xerox and have students cut apart the following pages of cards. When cutting, tell students to trim extra off of edges as edges will not match. Place one complete set in an envelope, one envelope per group (group size: 4). Provide each group with blank answer grids ( pages) and glue sticks (or tape) Students are to match the 4 representations Variations: Leave out of the envelope or three pieces (an equation from one row, a graph from another, a table from another). Students are required to generate the missing pieces. If students are working on graphing, leave out all of the graph pieces and require students to generate. If students are working on writing equations, leave out all of the equation pieces and require students to generate. LAUSD, Secondary Mathematics 009 1Adopted from Algebra Support Module

11 Verbal Description Tabular Representation Graph Symbolic Representation y is always x squared y = x This function is a direct variation with 4 times square of a number x y = 4x The opposite of half the value of x squared, when increased by results in the value of y y 1 = x + The sum of x squared and y is y = x + 4 y is a sum of 4 and the square of a number x y = x + 4 LAUSD, Secondary Mathematics 009 Adopted from Algebra Support Module

12 y is equal to the sum of and twice the square of a number x y = + x Double the square of x is equal to y increased by y = x 3 y is equal to the opposite of a square of a number x y = x The difference of y and double the square of a number x equals the sum of 4 and triple a number x y x 3x = + +4 The sum of y and half of a number squared equals the sum of that number and = + + y x x LAUSD, Secondary Mathematics 009 3Adopted from Algebra Support Module

14 On Your Own Using the Language of Comparison and Contrast Listening & Speaking Page 1 1. Think about how (x+ 1)( x+ 4) and x + 9x+ 4 compare.. Fill in the blanks for both the Comparison Questions. Comparison Questions How are and similar? and are similar because both. What do and have in common? Both and have/are. How is like? Like, is/has. What is a significant similarity between and? A significant similarity between and is. What is another important comparison between and? Another important comparison between and is because. With Your Partner: practice speaking and listening to the language of comparison. 1. First Partner 1 one reads the Initiator questions and Partner answers as the Responder.. Then switch roles: Partner is the Initiator and Partner 1 is the Responder.
