=Summary=

===Students will design a mat that that heats a pool of water. Students select and use a variety of problem solving strategies, both algebraic and graphical, with and without technology, to analyze quadratic equations over real numbers, communicate results and justify solutions in a clear and concise manner when solving real-world problems. ===

=CCSS Alignment for Grades 9-12=


 * ===**A-REI.7 ****: **// Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = –3x and the circle x2 + y2 = 3. // Students will solve quadratic equations over the set of complex numbers: apply the techniques of factoring, completing the square, and the quadratic formula; use the discriminate to determine the number and nature of the roots; identify the maxima and minima; use words, graphs, tables, and equations to generate and analyze solutions to practical problems. ===
