These shark bookmarks are just adorable and oh! so simple to make. Using either construction paper or the template included with the Sharks & Rays Science Unit available on Teachers Pay Teachers. Simply print out the template, trace onto construction paper or use as-is. Glue on the shark’s mouth and teeth. Fold along the dotted lines, and glue together. Cut the three triangles that make up the fins and glue in the location of your desire.
