Common Core (Vector and Matrix Quantities)
Common Core for Mathematics
Examples, solutions, videos, and lessons to help High School students learn to add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes.
Suggested Learning Targets
- I can add vectors graphically using the Parallelogram Method.
- I can add vectors using the Parallelogram Method, Law of Cosines and Law of Sines.
- I can add vectors graphically using the End-to-End method.
- I can add vectors using the End-to-End method, Law of Cosines and Law of Sines.
- I can add vectors using the Component Method.
