111.4.b.9

(9) Geometry and measurement. The student applies mathematical process standards to select and use units to describe length, area, and time. The student is expected to:

• (A) find the length of objects using concrete models for standard units of length;

• (B) describe the inverse relationship between the size of the unit and the number of units needed to equal the length of an object;

• (C) represent whole numbers as distances from any given location on a number line;

• (D) determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes;

• (E) determine a solution to a problem involving length, including estimating lengths;

• (F) 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; and

• (G) read and write time to the nearest one-minute increment using analog and digital clocks and distinguish between a.m. and p.m.
