Strand: MEASUREMENT AND DATA (1.MD.)

Measure lengths indirectly and by iterating length units (Standards 1-2). Tell and write time (Standard 3). Represent and interpret data (Standard 4). Identify the value of coins (Standard 5).

Standard 1.MD.1

Order three objects by length; compare the lengths of two objects indirectly by using a third object.

• Grade 1 Math Module 3: Ordering and Comparing Length Measurements as Numbers (EngageNY)
  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.
• Measurement and Data (1.MD) - First Grade Core Guide
  The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for First Grade Mathematics - Measurement and Data (1.MD)
