Description	A linear graphing lesson using the aircraft SR-71 as an “attention getter” and providing a reason to discuss temperature with relation to aerospace.
Comments	I have found the majority of my students have some interest in space exploration and aerospace. On her main web site: (http://daniel.calpoly.edu/~dfrc/Robin) Robin has many wonderful lesson plans combining aerospace science and mathematics. Many of the lessons can be modified to accommodate any age or skill level.

Web Site Author(s) or Sponsor	Michael Murray
Appropriate Grade(s) and Content Area(s)	Algebra II
Primary Use	Instruction for students
SD Grade Level Standard(s)	Algebra standard: solve linear-quadratic and quadratic-quadratic systems of equations algebraically and graphically.
Description	This web site contains two easy to follow examples of solving linear-quadratic system of equations.
Comments	The site reviewed is part of a larger site: New York High School Regents Exam Prep Center () that contains a wide variety of teacher resources, student help and practice questions on many of the SD math standard topics. Several of the projects that I looked at were very interesting and looked like they would work well in the classroom.

SD Grade Level Standard(s)	Algebra Standards: Select, justify, and apply a technique to solve quadratic equations over the set of complex numbers and interpret the results graphically. Analyze the relationships among the coefficients, factors and roots of polynomials. Solve linear-quadratic and quadratic-quadratic systems of equations algebraically and graphically. Create algebraic models to represent problem situations Determine roots of polynomial functions including complex roots. Determine equations for lines meeting certain conditions. Solve problems using the quadratic formula including graphic representation and analysis.
Description	This site contains tutorials for students including practice quizzes and tests. The tutorials are well prepared and easy to follow. The practice tests have a good representation of typical problems at this level. I would recommend this site for students that may want some additional help on specific topics.
Comments	The main site () includes tutorials on a variety of Pre-Calculus topics. The site also includes an on line mathematics chat for homework help, etc. The site graphics are appropriate and enhance the tutorials. There are many additional mathematical links included also.
