Last year after seeing (what seemed like) everyone raving about Estimation180.com, I jumped on the bandwagon. The first couple ones we did randomly, just when we had a couple extra minutes at the end of the period here or there. Well the kids absolutely loved it. They would ask me fairly often if we could play "that game" and when I didn't know what that meant, it was "that game with how tall that guy is"Somewhere around the same time I picked up the game Wits and Wages thinking it would be a […]

However, I didn't want to add my own material there. And as of

By using (say) DeMoivre's theorem, we have that \( \left( \cos\frac{2 \pi}{5}+ i \sin\frac{2\pi}{5} \right)^5=1\)Expanding the left side as the fifth power of a binomial, equating the imaginary parts on both sides of the equation, and then replacing \( \sin^2 72^\circ\) with \(1- \cos^2 72^\circ \) \( i\sin 72^\circ \left(5 \cos^4 72^\circ+10 \cos^2 72^\circ i^2 \sin ^2 72 ^\circ+ i^4 \sin^4 72^\circ \right)=0i\) \(16 \cos^4 72^\circ - 12 \cos^2 72^\circ

Dan Meyer provided our district’s math department with two days of PD in June. I liked the homework he assigned to us, and I’m in the process of merging his idea with a problem-solving plan for a longer-term mini-project of sorts. … Continue reading →
