2010-11 Improving Students' Understanding of Geometry Grants Recipient

"BRIDGING" the Gap in GEOMETRY!

Principles and Standards for School Mathematics calls for Geometry to be learned using concrete models and drawings. In this hands-on project, students will first design a blueprint, then build an authentic, replica, scale model version of a "Warren/Pratt" Truss Railroad Bridge. Students will be able to recognize, apply and reinforce numerous Geometry Standards by constructing a model "truss" bridge. The students will be actively engaged throughout the construction process from the 2-Dimensional design of the bridge using Dynamic Geometry Software & numerous tools; ruler, protractor, and blueprint to the actual 3-Dimensional construction using real Basswood stock and a mitre-box to make exact angle cuts (30 degree, 60 degree, 90 degree), which reinforce angle measurements and structural design. Through a hands-on approach the students will develop critical thinking and problem solving skills so necessary to maintain a strong, engaging, 21st Century Math Mind!
