Give your students a visual understanding of size variation as a fun introduction to early math skills. The worms come in 6 colors and 4 sizes: 1",2", 3", and 4" lengths. Use them for sequencing, categorizing and sorting by length and color. The instructor can use them for "Give me the longest red one", "Point to all of the shortest ones" or "Pick up all of the blue ones". An activity guide is included along with a handy storage bucket.
