Students who use braille and print can work together using the labels and tactile symbols to arrange the hexagonal tiles and connecting arrows to form a nitrogen cycle. Print lettering is inset so that it does not cause tactual interference for touch readers. Connectors have not been incorporated into the design so that students can move the pieces around quickly. It is recommended that the pieces be used on a non-slip surface, or that non-slip matting be added to the base of the tiles. Magnets could also be added. There are two elbow arrows due to the shapes required. It is suggested one is used to connect the soil (nitrates) tile to the plants tile. Note that the three soil tiles are labelled twice for clarify. Tiles included: animals, atmosphere, decomposers, plants, soil (ammonia), soil (nitrites), soil (nitrates), arrows, arrows elbow (L-R) and arrows elbow (R-L)

Print at least 10 arrows and one each of the elbow arrows
