1.2.3 understand the concept of rate and how to calculate rates and determine units 1.2.4 understand that precision is related to the unit of measurement used and the calibration of the measurement tools 1.2.5 use estimation to obtain reasonable approximations, for example, estimating the length and width of the playground to approximate its area 1.2.6 understand the benefits of standard units of measurement for both direct and indirect units 1.2.7 understand the relationship among units within both the US and metric systems 1.2.8 select and use tools that will provide an appropriate degree of precision, for example, using meters vs. kilometers 1.3.1 use the properties and relationships of plane geometry to describe shapes and figures including angles, degrees in a circle, triangles, isosceles, equilateral, or quadrilateral 1.3.2 Identify, describe, or draw objects in the surrounding environment in geometric terms, for example, producing a simple scale drawing of a classroom 1.3.3 understand symmetry, congruence, and similarity;
