I put shredded paper in the water table, and added magnetic items, and magnet wands, the children can go on a treasure hunt for different items. Make sure you give them a cup to place their finds in!
I put the magnet marbles in with cornmeal and the magnet wands. Then I lay Plexiglas on top so they can maneuver the marbles with the wands from underneath
Screw (new) cookie sheets into a wall that is low for the children to reach and let them play with the magnetic numbers and letter. It works great!!!
