In this semester we had two major units. The first one was about triangles and basic trigonometry. This unit taught me a lot, since I hadn't learned anything about this in the past. Below is the link to my portfolio which has everything I learned in that unit.
The other unit we had was shorter but I still learned a lot. It was about data, how to read and understand it. We learned about normal distribution and standard deviation. The link to my portfolio for that unit is below.
