Math-Kitecture, designed by Charles Bender, "is about using Architecture to do Math (and vice versa)." The author provides suggested activities that engage students in doing real-life architecture while learning estimation, measuring skills, proportion, and ratios. The main activity is for students to hand-draft a floor plan of their classroom to scale and then use software to create a computer-aided design (CAD) version, which can then be submitted and added to the online gallery. To assist students in the process, Bender has posted examples of floor plans, guidelines for creating scale drawings, and instructions on how to use computer software such as AppleWorks (ClarisWorks) or MS Powerpoint to create the computer version of the drawing. Also posted is a large collection of links to other web resources on architecture and mathematics. Additional Math-Kitecture "Architivities" include finding geometric shapes in buildings and structures (both on the computer and off), designing a dream bedroom, and exploring a 3-D model of a Frank Lloyd Wright house to estimate volume and surface area. Also highlighted are the performance standards for middle school mathematics and core curriculum for grades seven and eight that are met through these activities. Teachers are invited to send in additions to the section on Teacher's Notes, which posts lesson plans, ideas, and reviews sent in by teachers.
