Standard 4.MD.7
Recognize angle measure as additive.
A. Understand that when an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts.
B. Solve addition and subtraction problems to find unknown angles on a diagram in real-world and mathematical problems, for example by using an equation with a symbol for the unknown angle measure.
Explanation: This is a fun standard. We are just learning that you can add angles together to make a bigger angle. If you add, for example, 50 degrees to 20 degrees, you would get 70 degrees.
