Trick-or-treating took on a whole new meaning at Western Hills Elementary during the school’s community Monster Math Night.

“We get leftover pumpkins and give them to the students to take home, carve, and bring back the following morning,” explained Western Hills principal Mardel Higginson. “It’s quite a sight.”
