Have you ever done something special for Pi Day 3/14?? Here are some nice contest activities geared to encourage students to see connections between math and other areas.? Please download the attachment.? You can send projects via mail so entrance into these competitions is not limited to Long Island.?

Subject: PI question - re: transformations

Question 1:

In the transformations PI: GG61 they specifically mention that we need to
do rotations about the origin in a counterclockwise direction of 90 degr,
180 degr.
They don't mention negative numbers, they don't mention 270 degr.

Do you think that these (negatives, 270) are covered under the first "GG54
Define investigate and apply isometries in the plane". - maybe they will
have to do part one MC or part two basic type questions?

And for GG61 - they won't have to do a "big problem" with the negatives,
nor 270?

Question 2:
Also, do you think they will have to do any dilations with center not at
the origin?
GG61 says centered at the origin -
But, other GG mention "similarities". For example, maybe they'll have to
dilate something not on a graph grid? IDK am I just worrying myself

Thanks for your input!

I am often awake at night worrying about what kinds of crazy Geometry
problems the state is going to come up with! :-/
