Add And Decompose Angles To Solve Problems Math Games

In this series of games, your students will learn to recognize angle measure as additive. The Add And Decompose Angles To Solve Problems learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 4.MD.C.7 as written in the common core national math standards.

Concepts Covered

Angles are measured with reference to a circle with its center at the common endpoint of the rays and the rays intersection points in relation to their fraction of the circular arc. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and degrees are the unit used to measure angles. Present angles in a variety of situations; shapes, maps, slopes, openings. Angles can be added together or decomposed into non-overlapping parts. The angle measure of the whole is the sum of the angle measures of the parts. Find the measurements of unknown angles on a diagram in real-world and mathematical problems.

Two angles are called complementary if their measurements have the sum of 90. Two angles are called supplementary if their measurements have the sum of 180. Two angles with the same vertex that overlap only at a boundary (i.e., share a side) are called adjacent angles. Decompose an angle measurement. Recognize angle measurement as the additive of the decomposed angle. Solve problems involving unknown angles. Write an equation with a symbol for an unknown angle measure.
