Big Ideas: Length measurements can be estimated using appropriate known referents (benchmarks). This lesson builds on students' work with measuring with standard units. This task helps students develop visual measurement benchmarks. This work will help students in making reasonable estimates with measurement lengths. The mathematical concepts in this lesson builds toward students' future work with estimation and measurement. Vocabulary: about, a little less than, a little more than, longer, shorter, measure, standards units, units, customary, metric, inch, foot, centimeter, tools, meter, centimeter, ruler, yardstick, meter stick, measuring tape, estimate, sums, differences Special Materials: ruler classroom money: dollar bills and quarters (money needs to be true to original size) base ten blocks color tiles paper clip yardstick meter stick
