More to be reported on later, but did the chaos game with a couple of classes.

Love the whiteboard in the back. This was a tough proof for the pre-calc h group. Sticking points: understanding the summation form with the three variables, i,n, and k, and manipulating the algebra to get what was necessary.

Here what some students staying after came up with to avoid the typical "off-by-one" error that many students get tripped up on.

Warmup after winter break in PreCalc H. Find the area and perimeter of one section of a hexagon inscribed in a circle. Sector Area, and Arc Length. Whiteboarding. Gallery Walk of whiteboards.

Started with this activity with the pre-calculus students. The group with the closest measurement to 1 radian got a prize, as measured by one of Jen Silverman's Radian Protractor. Here's my entry (done with a straight edge and rubber band in less than 30 sec).

We had a lot of discussion rega...

Nothing from class today, just an observation. I was taking a picture of this paper and ended up talking to the guy in charge of ordering and delivering it all. This is only 1/3 of the paper that our high school uses every year. Even more impressive (?) is that the elementary school (k-3) uses 36 pa...

Here are students going over their quarterly (25 questions, multiple choice. Great data, mostly useless). I gave them back their quarterly but all they knew was the grade. In their groups they tried to agree about the correct answer for groups of 5. Good stuff.

Nothing to see here.

Review for the final exam in Advanced Algebra. I found the average of each standard and made review stations for the 4 lowest. They had a choice of where to go, 10 min a station. Worked great, love it.

Picture of the kid as penance for me not taking enough pictures.
