2.5 year old learning at day care issues

When talking to day care lady today she tells me son isn't learning as quickly as the others as he is distracted and doesn't pay as much attention as the others. She says he knows the things she is teaching, but is too stubborn at time to want to do what she is asking. I asked for assistance on how to help him with this, and she offered nothing. I want him to succeed as much as possible. Part of me says it is his age (what 2 year old will sit for 20 minutes circling the shapes?) but she seems very frustrated with him, but is not offering anything to help me. He listens for the most part at home and I have few discipline issues overall. Any help would be appreciated.
