Youtube Presents Measuring angles using protractors an educational video resources on mathematics.
Measuring angles using protractors is a free educational video by chris chlebek.It helps students in grades 4 practice the following standards 4.MD.6,4.MD.7,.
1. 4.MD.6 : Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure..
2. 4.MD.7 : Recognize angle measure as additive. 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. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure..
