I use a 4-group rotation system as a way to teach math. These headers can be put in a pocket chart, tri-fold, or on a bulletin board. There is also a sign for each letter where teachers can write the standard, an "I can statement," or the student's assignment.
M - Meet with Teacher
A - At your Seat (independent work)
T - Technology
H - Hands on Game (game usually relates to unit being taught)
