o Answer Keys - Fortunately for the teacher, there is not much grading to do. The only major written work is found in the Unit Circle section. Students can practice using the Kahn Academy software. When they sign in, they need to add the teacher as a coach so that the teacher can track their progress.

o Anticipated student actions, student difficulties, possible misconceptions - In order to be successful in this unit, students need a strong background in the Pythagorean Theorem. There is a review of it, but the teacher should make sure that students are confident in solving right triangles using the theorem before diving too deep into the lesson. Therefore, a link to practice with the Kahn Academy is included in the student's lesson. Keep track of their progress by becoming their coach through the website.
o Technical issues that may arise - All of the Geogebra applets were created by the author of this unit, and they should not fail at doing what they were created to do. The Kahn Academy applets could be unresponsive if the website goes down. In that case, just use the supplemental worksheets. If you do not have internet access, the Geogebra files and student handouts are available to download.
o Questions to the students - As a summative assessment, walk around and check that the students are on task and not struggling. Before each major activity, pause the class and have a discussion over what they have completed and the conjectures they have made. Be sure that all students have derived the correct formulas before moving into the next topic.
o Sequencing of student responses - The guided questions are designed to follow a logical path to make conjectures on trigonometric ratios. The responses can be found in the above answer keys.
o Formative and summative assessment - During the lessons, students are asked to complete several Kahn Academy activities. Here, you will find an assessment of the unit which can be completed on paper.
