Read Carefully! This assignment must be turned in to your math teacher within two weeks of returning to
school. This assignment will be graded as a homework assignment. Your math teacher will be available for
questions about this assignment upon returning to school from 7:10 am until 7:30 am.
BRRRRRR! It is cold outside. I cannot think of a better time
to review what we have learned about integers. Take a
few moments to see what you remember about integers.
Print off this paper and complete the questions to the best
of your ability. If you do not have access to a printer,
complete the questions on a piece of paper. Throughout
your work, there will be various websites to help refresh
and review your knowledge about integers. Good Luck
and drink some hot cocoa!
