This track teaches students measurement including telling time, and how to use both the metric and customary systems to measure length, volume, and mass. This unit correlates with the Tennessee Framework Standard: ESTIMATION, MEASUREMENT, AND COMPUTATION: In order to develop understanding of Estimation, Measurement, and Computation, the mathematics curriculum should include problems which require students to apply appropriate tools and units of measurement, to develop effective estimation and computation strategies for producing reasonable results, and to calculate using appropriate tools such as mental mathematics, technology, manipulatives, and pencil-and-paper.
