Prerequisite Skills ~ VSC 3.B.1.a ~ Mathematics Grade 1 ~ School Improvement in Maryland

Prerequisite Skills: The prerequisite skills describe what concepts a student needs to understand before working on this concept.

Standard 3.0 Knowledge of Measurement

Topic B. Measurement Tools

Indicator 1. Measure in customary units

Objective a. Measure length of objects and pictures of objects to the nearest inch using a ruler

Prerequisite Skills
To measure with an inch ruler, students must first have: compared lengths of objects and discussed lengths using correct terminology, such as longer, shorter, about the same, from end to end, etc. used a variety of non-standard units to measure length (e.g., body parts as units, paper clips, toothpicks, straws); understood the measurement process using non-standard units; recognized the importance of proper placement of the measuring tool when measuring length (identify a common base line); and understood the need for a standard unit of measure.
