Learning Algebra is easy with Slim Goodbody s X-Team! For Middle & High School Students Ages 12+ Meet the X-team and join them as they use their logic and problem solving strategies to tackle tough academic challenges. Together with history's great mathematical minds ... you ll help solve the mystery of ALGEBRA with this fun and innovative path to learning math. 10 Programs in all! Intent and Mathematical Overview of Program: Polynomials (River of Time) focuses on different types of polynomial equations that are represented by symbols, graphs, tables, and geometric shapes. The concept of using a quadratic equation written in standard form and factoring it is introduced. The program ends with the introduction of the Quadratic Formula. The program begins with the X-team asking Holon to explain how he is able to send them back in time. Holon explains the phenomena through quadratic equations that are similar to the formulas used when an object is thrown into the air. The equations are shown along with the associated tables and graphs. Students can quickly see many relationships or patterns in the graph, such as the symmetry of parabolas. In the second segment of River of Time, students have the opportunity to solve a geometric problem involving area. The problem is presented before students see the symbolic representation that the X-team uses and thus they can be encouraged to use multiple ways to solve the problem. When students view the segment illustrating how the X-team solved the problem using algebra, they have the opportunity to think about the relationships between factors when the product is 0. While the process is not given step-by-step, students are exposed to the conceptual idea that if the product is 0, one or both of the factors must be 0. The final segment of River of Time ends with the X-team being given access to the Quadratic Formula. No formal discussion or use of the formula is done in the program but it allows you as the classroom teacher to make the link between the ideas about polynomials to the Quadratic Formula itself. If students have used Completing the Square as a method for solving quadratic equations, you can show how the Quadratic Formula was developed. Principles and Standards for School Mathematics The Principles and Standards for School Mathematics (National Council of Teachers of Mathematics, 2000) includes standards and benchmarks that are related and aligned with the mathematical presentation in this program. These principles and standards have been followed in this program for Grades 6-8 and 9-12.

Learning Algebra is easy with Slim Goodbody s X-Team! For Middle & High School Students Ages 12+ Meet the X-team and join them as they use their logic and problem solving strategies to tackle tough academic challenges. Together with history's great mathematical minds ... you ll help solve the mystery of ALGEBRA with this fun and innovative path to learning math. 10 Programs in all! Intent and Mathematical Overview of Program: Expressions(Denial) is program that focuses on equivalent algebraic expressions. Algebra TilesTM are used to model and demonstrate equivalency of expressions as students make generalizations about simplifying expressions. The program begins with the X-team encountering a situation in which they must use what they know about algebraic expressions to create equivalent expressions. The problems presented in the initial program sequence are reversibility type problems, that is, they give students the answer and students create the problem. This requires students to think differently as they, in a sense, have to work backwards from the answer. Students have the opportunity to develop the idea that there are multiple algebraic expressions that simplify to 10x. As the X-team travels to visit Cleopatra, they move from simple algebraic expressions to thinking about two-dimensional representations using area. The area of the rooms remains the same but the configurations of the Algebra TilesTM are varied. From this, students can explore the relationship between the dimensions of the rectangles and the area. They notice that the dimensions are equivalent even though they may be expressed differently in the symbolic representation. Regardless of the variances in the tiles representations, the dimensions are equivalent. The idea of using rectangular arrangements is not to introduce multiplication of algebraic expressions. Instead, it is an introduction to the idea that Algebra TilesTM are based on area. When they are placed in a rectangular arrangement, the total area of the rectangle can be represented by an algebraic expression that is the product of the length and width dimensions. The fact that multiple arrangements can be made that have the same area but with somewhat dimensions may be surprising to students.

Together with history's great mathematical minds ... you ll help solve the mystery of ALGEBRA with this fun and innovative path to learning math. 10 Programs in all! Intent and Mathematical Overview of Program: Factors (A Doorway Through) focuses on decomposing a number by its factors or on building a product given the factors. Algebra Tiles TM are used to demonstrate how products can be represented by an area model. The program begins with the X-team encountering a situation in which they work with whole numbers. Rather than listing the numerical factors of the whole numbers, the X-team is asked to find all rectangles that have a given area. As they compare the number of rectangles that can be made from the factors of a given number, the team begins to consider the relationship between the magnitude of the number and the number of factors. They sometimes make over-generalizations, assuming that as the magnitude of the number increases, the number of possible rectangles they can make also increases. The number of rectangles is explicitly linked to the integral factors in the initial segments of A Doorway Through. This helps students who sometimes do not see the relationships between the dimensions of the rectangle and its area with the factors in a numerical situation that they may be more comfortable with before moving to a more symbolic context. The numerical situation provides a means for you to discuss composite and prime numbers as well as finding ways of determining all integral factors by using prime factors. It is also an opportunity to consider the relationship between the number of factors and the type of number. For example, square numbers have an odd number of factors because one factor is repeated. From the numerical context, the X-team then moves to reversing the thinking used to decompose a number to composing an area given the dimensions but now in a symbolic context. By using materials similar to Algebra TilesTM, the X-team creates a rectangular area, forcing students to think conceptually about the relationship between the dimensions and area. Unusual symbols are used to represent the binomials that form the dimensions of the rectangular area. The solution process that the X-team uses can be generalized to any binomial multiplication.
