She should plan enrichment activities for the 15% who have already mastered the content. She should go ahead and teach the 3rd-grade standard and expect the 35% to perform better on the day she teaches it. She should pull the 35% into small groups focusing on the 2nd-grade standard before introducing the 3rd-grade content.
