Dear Family,
Our class is starting a new mathematics unit about geometry and measurement called 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.
Throughout the unit, students work toward these goals:
Benchmarks | Examples | ||||||
---|---|---|---|---|---|---|---|
Benchmark 1: Convert linear measurements from a larger unit to a smaller unit. | Ramona bought 2 yards of fabric. She needs 80 inches of fabric to make a dress. Does she have enough fabric? | ||||||
Benchmark 2: Determine the perimeter and area of rectangles, including using generalizable methods. | |||||||
Benchmark 3: Draw and identify lines and angles, including parallel and perpendicular lines, and classify polygons by properties of their sides and angles. |
