In Kelly Stevens’ kindergarten classroom, each day begins with circle time for what sounds like a menu of lesson options.

“Miss Stevens is calling friends to read at the green table,” Stevens says. “We’re constructing boats. We’re also constructing out of clay.”

Students Marco Carias Castellanos and Holden Free chose a writing activity on this day. But there’s no worksheet in front of them. Instead, they’re standing in front of wolf statues they made out of blocks. Their assignment is to write labels for each of its parts.
