MONTICELLO — As flurries swirled across an open field just west of here Thursday, a group of fifth-graders knelt in the snow for their technology lesson.
Bundled up in snow pants, face masks and mittens, the students practiced their coding skills by building shapes with blocks of snow using codes they had designed.
"I have two coats on right now — and heated socks and handwarmers," said 10-year-old Santana.
"But you don't need that stuff to be out here," piped in 11-year-old Kaitlyn, who said she just wears a lot of layers.
The fifth-graders are the oldest of the 180-or-so students in Monticello School District's Nature-Based Education program, which organizers say is the only nature-based curriculum for upper elementary grades in the state.
"We started looking at different programs and schools. We were never able to find anyone who did exactly what we do," said Liz Barnes, a third-grade teacher.
A sprinkling of public school districts and private institutions have started nature-based preschool or kindergarten programs in recent years, which is easier to plan because learning is more play-based in younger grades. But planning an outdoor curriculum for upper elementary grades — with social studies, math and STEM lessons — is more of a challenge.
Barnes, in her 15th year of teaching, said she had to reimagine how she thought about lessons. Now she sees sticks and trees as opportunities to learn about angles.
