We went over finding the arc length and sector area of circles through this foldable that I created last year. I did make some minor edits that I really ended up liking! We filled out the yellow sector area and arc length graphic organizer before starting the foldable. I know that it's not in the pictures but underneath the yellow graphic organizer, I had students write down Arc Length = Crust of Pizza and Sector Area = Slice of Pizza..... Students seemed to understand the difference after that food analogy!
I can't really post any misunderstandings that students had over this lesson because students ROCKED it! However, I did make it a point that to mention that this was the last time that I will probably ever teach them (this actually shocked quite a few).
After the foldable, I handed them their very last HW assignment =( Many were too excited and finished it too fast.
I will be posting yesterday's lessons over arcs and chords tonight or tomorrow (depending on how long I want to procrasinate studying for my test).
You can find the files that I used here:
The answer for example 4 in the arc length problem was a bit confusing for my students b/c they hard a hard time wrapping their heads around the angle measure being greater than 360 degrees. I explained to them that this is a 2nd rotation.
