Really Good Stuff EZ Stick Numbered Spot Markers and Labels help students learn to line up properly. Place them on the floor to indicate proper spacing, and have students stand on them when they line up. The decals stay put, but come up easily and leave no residue when removed. The set includes numbers 1– 32, as well as labels for Line Leader, Door Holder, Caboose, and Lights. You can stick them on your walls, too.
