Prof. Stirling-Durrant’s classes have been brushing up on their measurement skills.

Second-grade standards include:

Strand: MEASUREMENT AND DATA (2.MD) Measure and estimate lengths in standard units (Standards 2.MD.1–4) and relate addition and subtraction to length (Standards 2.MD.5–6). They work with time and money (Standards 2.MD.7–8). They represent and interpret data (Standards 2.MD.9–10).

Standard 2.MD.1 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

Standard 2.MD.2 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.

Standard 2.MD.3 Estimate lengths using units of inches, feet, centimeters, and meters.

Standard 2.MD.4 Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. For example, after measuring a pencil and a crayon, a student uses the measurements to determine that the pencil is two inches longer than the crayon.
