At the end of this lesson, students will be able to:
· Express the length of an object using centimeter cubes as length units to measure with no gaps or overlaps.
· Measure an object twice using different length units and compare; relate measurement to unit size.
Student Target
“I can use units to accurately measure objects.”
CCR Focus Standards
Geometry - Level A
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. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
Supporting Standards
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.
Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit
