Math Teasers

Time to exercise our "Math Brain Cells" again. Math Teasers will be here every Monday morning. Work out your problem, (show any work) put YOUR name, your grade. and your teacher's name on your paper and place it in my mailbox by Wednesday at 1:00pm. Winners will be announced on WCES news on Thursday mornings and you can go there after the news to get your prize. Weekly winners are on the winner's page. Good luck everyone!
