• Welcome back! Did you
have a good break?
• Entry Task:
• On the sticky handed
you as you walked in
(or on your desk),
describe your break in
3 words or less.
๏ฝ
I can determine an
inverse relationship
and create an
equation to describe
it.
Pun of the day:
(Thanksgiving Themed)
With a partner, you need a lab paper, a
pencil, ruler, tape, and 10 pennies
5. Graph your points (from the table) on a graph with
the number of pennies on the x-axis and the distance
from the fulcrum on the y-axis. Then draw a smooth
curve through your points.
Task
• On the same
sticky you did
your entry task
on, describe the
lesson in 3
words or less.
