NCTM Brain Teasers Sliding Triangle The triangle at left lies on a flat surface and is pushed at the top vertex. The length of the congruent sides does not change, but the angle between the two congruent sides will increase, and the base will stretch. Initially, the area of the triangle will increase, but eventually the area will decrease, continuing until the triangle collapses. What is the maximum area achieved during this process? This brainteaser was written by Derrick Niederman. Solution: 200 square units; 32 units. For the first part of the question, the maximum area occurs when the angle between the sides is a right angle. For a more advanced trigonometry solution, remember that the area of a triangle can be calculated by taking half the product of two sides and the sine of the angle between those sides. Again using a trig solution, A=(1/2)absinθ, where a and b are the side lengths.

MITx Opens for Enrollment (and Certification - For Now - Is Free) MIT opens registration today for the first of its online courses offered as part of its new MITx initiative. The university announced MITx late last year as the next step not just in informal online learning but in alternative certification. Registration for MITx is free and open to anyone, and for this first "prototype" class, there is no additional charge to receive the certification upon successful completion of the class. This first class is "6.002x: Circuits and Electronics." According to the course website, the class will demand approximately 10 hours a week from those enrolled. Circuits and Electronics, as the name of the course suggests, is meant to be an introduction for electrical engineering and computer science majors. But the connection to MIT OCW is important here, and it's something that makes MITx quite distinct from some of its online learning competitors.
The iPad Effect: A Top-10 List » Third Graders, Dreaming Big It’s only been a few months, but I’ve already noticed some drastic changes in our classroom when the iPads roll in…. I’ve labeled these Top-10 phenomena as being The iPad Effect, as they seem to occur every Tuesday and Thursday…. 1. Fewer Water Bubbler Visits Days when there are no iPads in the classroom, students seem to ask to leave to hydrate at the bubbler far more often than they do when the iPads ARE in the classroom. 2. We try to time our bathroom visits with regular breaks in our routine. 3. Seems that iPads are the latest cure for stomachaches, headaches, hang-nails, sore arms and legs and boo-boos. 4. I can say with confidence, during my eight years of teaching, I seldom have had students ask to do MORE work than what is required. 5. In a room full of students recording their voices, and playing them back, you would think that focusing would be more difficult. 6. Face it. 7. Students who are off-target in their behavior risk missing out on part of their iPad time. 8. 9. 10.
