Tuesday 9/21

Sorry for the late post. A lot going on today...

**Note: I will be staying after Thursday for extra help

Standard Math 7
HW: ASSISTments assignment
We will review in class tomorrow and continue work on data and graphs.


Pre-Algebra
HW: Text p. 38 #1-23 odd
PLEASE NOTE: I am unable to post the ASSISTments portion of the assignment right now. We will do it in class tomorrow (as long as technology cooperates!).

Great discussion in class today about "Thomas' Conjecture" which basically states that given only the circumference of a circle, you can never really know the exact area or given only the area, you can never know the exact circumference. Parents: See if your Pre-Algebra student can explain this. We had some great thinking in class!
