In This Unit of Study…
Students will become acquainted with benchmark units of measurement so they can estimate lengths to the nearest inch, foot, yard, centimeter, and meter. After estimating the length of an object, students will identify appropriate measurement tools and units for obtaining accurate measurements. When measuring objects with two different units, students will recognize that fewer of the larger units are required. They will also measure the length of two objects, using the same unit, and they will determine how much longer or shorter one object is than another. Students will also solve one- and two-step real-world measurement problems involving addition and subtraction of lengths given in the same unit. They are not expected to convert measurements.
B.E.S.T. Benchmarks:
- MA.2.M.1.1 Estimate and measure the length of an object to the nearest inch, foot, yard, centimeter or meter by selecting and using an appropriate tool.
- MA.2.M.1.2 Measure the lengths of two objects using the same unit and determine the difference between their measurements.
- MA.2.M.1.3 Solve one- and two-step real-world measurement problems involving addition and subtraction of lengths given in the same units.
Overarching Key Concepts:
- Estimate and measure lengths using customary and metric units
- Measure and compare to solve length problems
