7th grade Math

We have learned how to recreate shapes in the exact way they were but smaller or bigger. We also learned how two numbers can make a pattern that goes off of the exact same number over and over. Then we learned about the area, circumference, and radius of a circle and how the all revolve around PI, no, not the dessert, the number (3.141592654). We also learned about how to leave a (proper) tip and how to find percentages of things like groceries or test scores even. We also learned about how certain types of equations are solved by doing the opposite of what they tell you to do. Our last big unit was about Angles, Triangles and Side lengths.
