This power point presentation is intended to serve a review game at the end of a polynomial functions chapter. The talbe of questions is linked to the questions, which are linked to the answers. Students should work in group of four. They will need a whiteboard, marker, and eraser. Time given for each question is dependent upon difficulty.

The power point impacts student learning by allowing students to learn in multiple ways. By having students respond in groups of four, they use collaborative learning to reinforce their prior knowledge and encourage discourse by forcing students to agree upon one correct answer. Once the whole class has responded and received points if appropriate, the instructor provides feedback, whether in the form of encouragement or correction. Students are able to gain immediate feedback before a formal assessment on the unit. Students who are auditory, visual, and kinesthetic learners can all benefit from this power point. Here is the quiz show table. Each letter is hyperlinked to its corresponding question. Each answer slide is hyperlinked back to this main page.Click on the box to view the answer. Click on the rectangle to return to the question table. These 100 point questions should be answered fairly quickly. Limit work time.i squared equals -1Students must use correct method to earn credit.Students must use correct method to earn credit.Students must answer both questions to earn full points.Remind students of the formal rule.Remind students of the formal rules.Remind students of trick for remembering.This will take a great deal of time. Consider making this question double points.
