This lesson explains why measurement is important, standard units of measurement (such as inches, pounds, and pints) and non-standard units of measurement (steps, hand spans, cubes, and counters).
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.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.4: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard-length unit.
2.MD.9: Generate measurement data by measuring lengths of several objects to the nearest whole unit or by making repeated measurements of the same object.
