• This week you are introduced to a conceptual approach to understanding numbers and basic mathematical operations. Many of this week's concepts may be presented differently than you remember from grade school because the way foundational mathematics is taught has changed in the last few decades. This course uses newer and more effective instructional approaches. Choose a topic from the readings this week. Compare and contrast how you first learned about that topic with the way it is presented in this week's materials. What did you learn that you may not have expected? Give an example of how you can apply what you learned to a situation outside the classroom.
