I have 4 kids who KNOW EVERYTHING! I'm not sure why they're in 2nd grade cause they know it all. They only want to go over concepts one time. The 2nd time they blatantly express that they don't want to review or reteach the concept. This is very frustrating cause they don't have the grades to show any form of mastery, but they think they have it in the bag. This attitude happens in all subject areas. It's an even split of boys and girls who do this. They all are on grade level, but not above. Parents have been called, notes, texts, emails have been sent. This is an attitude thing that just hasn't been shaken.
Can you give me some ideas on how to help them see/understand that this is important?
