Dinosaur Roll-a-graph Pictograph. I used the blank templates from educationcubes.com, and printed the dinosaurs from here. I printed the large ones, which were too big for the template provided at that site, so I made my own and pieced it together. He then rolled the cube and glued on the dinosaur that came up each time. (I glued the initial one in each row before giving it to him).
This was graphing dinosaur fruit snacks, I used the fruit loops graph from here, we have used it for much more than fruit loops! He then graphed the snacks by colors.
