This lesson teaches measuring with inches, feet, and centimeters while using rulers, tape measures, and yardsticks. Students will compare sizes of objects as well as practice selecting the proper unit when measuring an object. (Most appropriate for grade levels K-2.)
Math Standards:
K.MD.2: Directly compare two objects with a measurable attribute in common to see which object has “more of” or “less of” the attribute and describe the difference.
1.MD.1: Order three objects by length; compare the lengths of two objects indirectly by using a third object.
1.MD.2: Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
2.MD.1: Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
2.MD.2: Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
2.MD.3: Estimate lengths using units of inches, feet, centimeters, and meters.
2.MD.4: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard-length unit.
