First, I made little magnets for each student by using glass beads and glass glue. I cut small circles from my old magazines and glued them to the back of the bead with the glass glue.
Then I used my trusty hot glue gun to attach magnets to the back. I used the smaller magnets this year and they were just as powerful as the larger size, plus a little cheaper!
I bought a fun package of calendar numbers and laminated them. You could make these easily as well. After attaching them on the back white board, put the magnets next to them.
Ta-Da! Now if we have papers to turn in, I can say "Put your homework on your magnet". I usually have a "helper" each week that will go back and collect them in order for me. Fourth graders are so amazing!
As an added bonus, I let the students take their magnet home at the end of the year. Mostly, I do that so that I get to make more each summer. Sometimes a teacher just needs a project...
