Sleeves rolled up, second-grader Isaak Barber shoved his hands into the recently hollowed-out 21-pound pumpkin.
He pulled out his hands, spilled four more seeds on the table and slumped down. Barber was well past his guess of 15 pumpkin seeds.
"There's still some seeds," Barber said.
His older brother Nick Retseck moved the pumpkin closer and dug his hands in, his longer arms able to reach the bottom.
"I got it, I got it," he said.
This wasn't Retseck's first "pumpkin day" at Sagewood Elementary School.
Retseck, now a senior at Kelly Walsh High School, attended second grade at Sagewood. Now, he was back at Sagewood to help his little brother and grandmother with the tough part of the project -- cutting open the pumpkin and cleaning out the insides.
For more than 20 years, Sagewood second-graders have completed math and science lessons with pumpkins and the help of a family member.
The school gym is filled with parents, grandparents, younger siblings and the smell of pumpkin pulp. Students measure the pumpkins' "bellies." They weigh the pumpkins. They estimate and then count seeds by tens -- they're learning place value.
All numbers are recorded on class charts that can be taken back to classrooms for analysis and discussion.
If time allows, students carve their pumpkins into jack-o'-lanterns.
"It's an easy way to get a jump start with pumpkin carving and learn math and science too," said Toni Billings, who teaches second grade at Sagewood. "It's a way to get parents up here at school."
Wednesday was Billings's 20th pumpkin day. The teachers may change, she said, but pumpkin day has stayed mostly the same.
Arlene Gallinger is a five-time pumpkin helper, finishing years of pumpkin day with her youngest daughter Kera. Teachers joked that she has more pumpkin days in the future -- with her grandchildren.
"I thought, 'Oh my gosh, I'll never get out of pumpkin day,'" Gallinger said. "But really, it's fun. The kids look forward to second grade because of pumpkin day."
They look back too.
Gallinger's oldest two sons still remember the event, and if they weren't working, Gallinger said, they would have been pumpkin helpers.
She still has their pumpkin day books and plans to find them later this week -- after she gets the pumpkin smell off her skin.
