This board may take some time to set up, but it will be worth it if you make the pieces durable using lamination. Using butcher paper and construction paper, make the parts of a cell that you study with your particular grade level. Laminate these and place Velcro stripping on the back. Have a large circle or square cell as the base of the board. Place the other side of Velcro stripping on appropriate areas of the cell. Have arrows pointing from these areas to empty spaces on the border of the board where students can place labels of the different cell parts. You can make the labels on word cards and punch holes in the top so students can hang them over push pins. You may also want to have them match descriptions along with the names.
