Keegan Kellogg sits at the front of his classroom, facing about 20 students. He points to their next assignment written on a letter-sized piece of white paper.
"It says, 'I learned a bunch in…?'" Kellogg asked.
"Kindergarten," replied the students.
Kellogg teaches at Jackson Elementary School in Greeley. Greeley-Evan School District 6 has offered free, full-day kindergarten for about 15 years. Next year, all school districts in the state will be able to offer the same.
