I found a few items around the house and classroom to use for this work. Then I drew a picture of each item with the heading "What is Magnetic?" The students place the item in the yes column if it is magnetic and then they color the picture on the paper. If it isn't magnetic then they place it in the no column and cross out the picture on the paper. Items that I used were: crayon, rubber band, pipe, plastic strawberry, paperclip, magnetic letter, nail, bandaid, dice, checker, triangle tangram and a bell.
