Module/Unit 3: Ordering & Comparing Length Measurements as Numbers
Module 3 begins by extending students’ kindergarten experiences with direct length comparison to indirect comparison whereby the length of one object is used to compare the lengths of two other objects. Longer than and shorter than are taken to a new level of precision by introducing the idea of a length unit. Students then explore the usefulness of measuring with similar units. The module closes with students representing and interpreting data.
It is important to note that the ruler is not introduced in the math program as a measurement tool until 2nd grade. The ruler is introduced in concert with the number line and the concept of halves and quarters. Students in first grade will measure objects with other objects to build their understanding of size and comparison.
Example: Compare the length of a string to the length of a book or use paperclips to measure the size of a pencil. The paperclips would be an example of a "nonstandard" unit of measurement. Students will measure objects with centimeter cubes, which is an example of a "standard" unit of measurement.
Students will also be introduced to simple graphing and interpreting data, for example in the context of comparing the number of students who might have one hobby compared to another hobby.
