Students explore measurement concepts using a variety of units of length (palms, footprints, centimeters, inches, meters, and yards). They develop a list of measurement rules and compare the relative size of these different units. Students then apply these measurement techniques as they determine "the best roller" in a collection of cars.

EXPECTATIONS
	Use this list of Expectations to assess students on the key concepts and skills in this unit.
E1*	Use words and symbols (e.g., <, >, =) to show comparisons of quantities (e.g., lengths).
E2*	Use and apply place value concepts and comparative language to compare and order lengths (e.g., shorter, longer, shortest, longest).
E3	Solve word problems (e.g., compare) involving length.
E4*	Recognize that the measure of a length is dependent on the size of the unit of measure (e.g., a pencil is 6 inches or 15 centimeters).
E5	Estimate length using nonstandard (palms, footprints) and standard (centimeters, meters, inches, feet, yards) units.
E6*	Measure length using nonstandard (palms, footprints) and standard (centimeters, meters, inches, feet, yards) units.
E7	Select and use appropriate measuring units (e.g., centimeters, meters, yards, inches, feet).
E8	Make a table, bar graph, and line plot to find information about a data set.
E9	Read a table, bar graph, and line plot to find information about a data set.
E10	Use a table, bar graph, and line plot to solve problems about a data set.
E11*	Use math fact strategies to add (direct modeling, counting strategies, reasoning from known facts) for the facts in Group E (5 + 7, 8 + 4, 8 + 5, 9 + 3, 9 + 4, 9 + 5, 10 + 1, 10 + 2, 10 + 3).
E12*	Determine the unknown number in an addition or subtraction sentence relating three whole numbers for the facts in Group E.
