* Individual Think Time *
What to do if you get stuck...1. Reread the problem. Did you
write it
down correctly?2. Reread your notes. Is there a problem
similar that we did together in class?3. Find a problem similar
in your book. Try
this one to see if it helps.4. Skip the problem until the end
of
Individual Think Time. Then ask an "educated" question of a
neighbor or Mrs. Call.
