o ONLINE LEARNING ACTIVITIES: Many students find the PLATO (or BuzMath, where available) online activities to be a good place to get started on a given lesson, since …

▫ The PLATO Tutorials (or BuzMath Discussions/Demonstrations [where available]) generally present a good introduction to the critical concepts and skills.

▫ The PLATO Applications (or BuzMath Guided Practices & Independent Practices [where available]) provide a fair amount of reinforcement and practice.

▫ And the BuzMath Self Checks [where available] are a good measure of how well you have learned the material and what things you still need to work on, if any.

You are STRONGLY ENCOURAGED to take advantage of these online resources; however, they are not required. The main thing is that you be able to demonstrate that you have learned the required concepts and skills by passing a written Cumulative Evaluation with at least 70%.
