Here is a short video explaining my project in case you choose to purchase.

Perfect for cooperative learning groups, math centers, or simply if a student asks for extra credit. There are three printable PDF lessons and the fourth PDF is a teacher graded quiz to prove mastery.
The teacher can provide printouts of each lesson. Each of the three lessons take about 30-40 minutes to complete. There are 5 problems in every lesson and also in the final quiz. The PowerPoint gives step-by-step animated solutions along with detailed explanations for all problems. Students should be able to clearly understand the solutions as they work through Lessons 1-3. Also, students can review the animated solutions as needed. When a student feels ready they can ask for the final quiz to prove mastery.
The final quiz is teacher graded and never returned to the student in case they choose to retake the quiz for a second chance. I do have a Version #2 coming out soon.
