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)
2. The Pumpkin Project
Third grade teacher Alycia Zimmerman, a self-described Ms. Frizzle wannabe, created this awesome lesson plan that melds standards-based math and science content with slimy, tactile teamwork. Check out the full lesson plan and downloadable qualitative and quantitative data worksheets. (Grades 3–5)
3. Trick-or-Treat Math Riddle
Kids will love figuring out this Trick-or-Treat Math Riddle where they listen to the story of Max’s spooky Trick-or-Treat math adventure. Teachers can read the story or play an audio version. (Grades K–2)
4. Fun with Candy Corn
Find out if a pumpkin floats—and why, or why not. What about a really large pumpkin? You’d be surprised. Have students wrap a string around a pumpkin and guess the size (circumference). For extra credit figure out the diameter (hint: 3.14 × diameter = circumference).
8. Halloween Fun with Place Values
Young kids will love this interactive game of matching cards that teaches place value, matching, and simple addition.
10. Just for Fun
This video shows a man rafting a 1,200-pound pumpkin through Class 3 white water rapids in the mighty Colorado River!
