We then did a quick review on Dimensions using sketchpad. We talked about the radius of a circle, chords, and the diameter of a circle.
We also reviewed the easiest way to measure the circumference of a circle manually. If you can unfold the circle into a straight line then measure the length, you would have found the diameter the easiest way.
C= circumference, d= diameter, r= radius, π=pi
C= 2πr or C=πd
d=2r or d=C/π
r=d/2 or r=C/2π
π=C/d
Then Jojo checked our homework. Speaking of homework everyone remember to SHOW YOUR WORK!!!!!!!!!
We then put problem numbers under two categories. The first category being Yes Sirrr! meaning you felt comfortable with the problems. The second was NSG meaning not so good. At the beginning we all seemed pretty confident. Then we looked at the answers and some of the problems we thought Yes Sirrr's!!! quickly changed into NSG's. Based on who got which problems wrong we split up into groups to help each other to be able to explain each problem mathematically as well as correctly. We did our best to explain the problems thoroughly to one another. Then the we went up to the board one by one to explain how to do the problems and what we had done wrong the first time. Tomorrow we will finish it all up.
Here are a few videos that although not the best sounding or entertaining, will help some of us. As Jojo would say this is HOT!!!
