Bulletin Boards
I truly believe that bulletin boards can not only convey information (announcements), decorate the room (fall, Christmas, etc.), but can, and SHOULD, also teach a new mathematical topic.
Each day the fractional part of the year is
calculated. At the beginning of the day the new decimal, percent, and ratio are calculated
and posted.
Outside my room is a major hallway.
For the first time this year, I used it as a bulletin board! So far I have put
up only a couple of math ideas:
5^2 means 5 x 5 = 25 and 10^0 is actually = 1
The goal is put up a big display (12" letters) that everyone will notice! If enough people see it often enough, they will at least have a visual memory of the fact or idea! Even the sixth graders, eighth graders, high school teachers, parents, and visitors will see it many times.
Other problems:
What is 10% of 45? How many minutes are in 5.2 hours?
