Measurement and Data Measure and estimate lengths in standard units AR.Math.Content.2.MD.A.1 Measure the length of an object by selecting and appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes AR.Math.Content.2.MD.A.2 Measure the length of an object with two different length units Describe how the two measurements relate to the size of the unit chosen For example: A desktop is measured in both centimeters and inches. Student compares the size of the unit of measure and the number of units. AR.Math.Content.2.MD.A.3 Estimate lengths using units of inches, feet, centimeters, and meters AR.Math.Content.2.MD.A.4 Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit Measurement and Data Relate addition and subtraction to length AR.Math.Content.2.MD.B.5 Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, and write equations with a symbol for the unknown number to represent the problem AR.Math.Content.2.MD.B.6 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and solve addition and subtraction problems within 100 on the number line diagram
