1.7 Geometry and measurement. The student applies mathematical process standards to select and use units to describe length and time. The student is expected to:
(B) 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;
