The PowerPoint presentations below were created to complement the third- and fourth-grade math standards as covered in Spirit Lake. These are mostly under Common Core Number and Operations in Base 10 standards . (If your school hasn’t adopted Common Core, I bet you still teach addition, subtraction, multiplication, division and how to compute a perimeter.) Feel free to download.
