Pumpkins and Jack-o-Lanterns preschool activities. Pick, scoop, count, and explore—it’s time for a week of pumpkin learning fun! Our pumpkin preschool and kindergarten weekly plan is packed with engaging pumpkin activities, crafts, games, songs, literacy and math activities, science experiments, and printables. Children explore pumpkin life cycles, pumpkin parts, seeds, vines, pumpkin patches, counting, measuring, shapes, and fall while building early literacy, math, science, fine motor, and observation skills through playful, hands-on learning.
