Take a stab at it.

KWBAT Demonstrate Mastery of unit learning objectives on a practice test

So yesterday during class and for homework students were to complete the conceptual study guide. Today they will take a practice test using their study guide to see if they are still are having difficulty in certain areas. Using the study guide during the practice serves two purposes, It first shows how doing the homework is beneficial to assessments, two it shows how the concepts are applied to questioning and comprehension. If students had the concepts right on their study guide and get a question wrong they have issues with application of the concept or understanding the question. If students did not have the concept correct on their study guide, that would be an area they need to go and review for the test because they still dont understand the concept or did not take time out to complete the study guide,
