Unit 4- Measuring and Classifying Shapes
During this unit, students measure lengths using U.S. standard units (inches, feet, yards) and metric units (centimeters, meters), convert measurements from larger units to smaller units within the same measurement system (for example, from feet to inches), and measure perimeters. They classify quadrilaterals and triangles based on specific characteristics. They measure angles using other angles as references and using a protractor. Students also solve problems about area, the two-dimensional measure of the size of a surface.
