They offer a short way to reach and explain: - trigonometry - the Pythagorean theorem - trig formulas for dot- and cross-products - the cosine law - a converse to the Pythagorean Theorem http://whyslopes.com/freeAccess/distributiveLaw.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- NASA CONNECT http://connect.larc.nasa.gov NASA CONNECT is an annual series of free integrated mathematics, science, and technology instructional distance learning programs for students in grades 5-8. Each program has three components: - a 30-minute television broadcast, which can be viewed live or taped for later use - an interactive web activity which provides educators an opportunity to use technology in the classroom setting - a lesson guide describing a hands-on activity These three components -- television broadcast, web activity, and lesson guide -- are designed as an integrated instructional package. Registered educators will receive, via e-mail, the date of upcoming shows, a show summary, and a PDF version of the lesson guide. http://connect.larc.nasa.gov/register.html NASA CONNECT seeks to establish a "connection" between the mathematics, science, and technology concepts taught in the classroom and the mathematics, science, and technology used every day by NASA researchers. By demonstrating the processes of creativity, critical thinking, and problem solving skills, NASA CONNECT enhances and enriches mathematics, science, and technology education. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- DARE TO FLY WITH CLASS New Brunswick Public School District http://www.geocities.com/daretofly2001/ A collaborative project designed to give students in grades 3-5 an opportunity to: - display their aerodynamic and creative talents - use patterns to create two different styles of paper airplanes - determine which type of paper airplane will fly the greatest distance and stay aloft the longest time Registration ends February 1, 2002 with results due no later than February 28. http://www.geocities.com/daretofly2001/rules.html There are 4 forces of flight: lift, drag, thrust, and weight (gravity). Teacher pages with information on some introductory hands-on activities are available: http://www.geocities.com/daretofly2001/teacher.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Mathematics Library http://mathforum.org/library/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ |
