17 Spooktacular Math Activities for Fall

1. Eyeball Estimation

Fill three to five jars with slimy peeled grapes (or rubber balls), add a little red, purple, or orange food coloring, and ask students to estimate how many “eyeballs” are in each jar. For older students, have them use the different numbers of eyeballs to see how many math equations they can come up with. Try putting grapes in tonic water and turn out the lights—it glows in the dark! (Grades K–5)
