Using Overhead Manipulatives Have students work in groups to do this Mini- Project. It deals with solving rational equations. Also, the work involves a review of adding, subtracting, multiplying, and dividing rational expressions. There are twelve exercises to do. Students must simplify their answers. Next, they cut out each rectangle displaying the answer to the exercise. Then students match each rectangle with another one with the same answer. Allow each group to explain how they solved at least one of the exercises. Let them answer any questions about their work. See how many groups discovered the mathematical relationship of the answers. Answers A, 1; B, 4; C, 3; D, 2; E, 5; F, 6; G, 4; H, 6; I, 2; J, 1; K, 5; L, 3 Match A, J; B, G; C, L; D, I; E, K; F, H They are the first six natural numbers. © Glencoe/McGraw-Hill 194 Teaching Algebra with Manipulatives
Using Overhead Manipulatives (Use with Algebra 1, Lesson 12-5) Dividing Polynomials by Monomials and by Binomials Objective Model dividing a polynomial by a monomial and by a binomial. Materials • product mat transparency* • algebra tiles* • transparency pen* • two blank transparencies * available in Overhead Manipulative Resources Demonstration 1 Dividing a Binomial by a Monomial • Point out that algebra tiles used in previous activities are based on the fact that the area of a rectangle is the product of its width and length. Tell students they will use algebra tiles to build rectangles to find quotients. • Tell students you want to find (2x 2 6x) 2x. • Ask students how to model 2x 2 6x. Use 2 x 2 tiles and 6 x tiles. x 2 x 2 x x x x x x • Display the product mat transparency. Place 2 x 2 tiles at the corner of the product mat. Then place one of the x tiles as shown. 2x x 2 x 2 x • Ask students how to complete the rectangle on the product mat. Place 3 x tiles under the first x 2 tile, and 2 x tiles under the second x 2 tile • Have students identify the length and width of the rectangle. length, 2x; width, x 3 • Ask students which dimension of the rectangle represents the quotient of 2x 2 6x and 2x. the width • Have them identify the quotient. x 3 Write (2x 2 6x) 2x x 3 on the transparency. x 3 2x x 2 x 2 x x x x x x Algebra 1—Chapter 12 © Glencoe/McGraw-Hill 195 Teaching Algebra with Manipulatives
