1.7A Use measuring tools to measure the
length of objects to reinforce the
continuous nature of linear measurement
1.7B Illustrate that the length of an object is
the number of same-size units of length
that, when laid end-to-end with no gaps
or overlaps, reach from one end of the object to the other
1.7C Measure the same object/distance with
units of two different lengths and
describe how and why the measurement differ
1.7 D Describe a length to the nearest whole
unit using a number and a unit

The student applies mathematical process standards to select and use units to describe length, area, and time.
2.9F
Use concrete models of square units to find the area of a rectangle by covering it with no gaps or overlaps, counting to find the total number of square units, and describing the measurement using a number and the unit
