Reminder: the baseline assessment is a celebration of all their learning and should be presented as a great opportunity to showcase everything they know. Remind them that all outcomes will be assessed, not just the 10 questions from the foundational quizzes. One way I had students buy in was by saying, "This is hard, and therefore it will be the end of regular math classes for the year, and we will be celebrating once everyone has written it." (ideas - no more math, math games, outside time, pizza party, ice cream)
To prepare students for the year-end assessment, you should plan for a two-week consolidation of learning. You want to plan for activities, games, or projects that review all of the covered outcomes.
