Domain-Subdomain #: MAFS.K.MD.1.aArchived Standard

Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

Subject Area: Mathematics
Grade: K
Domain-Subdomain: Measurement and Data
Cluster: Describe and compare measurable attributes. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Formative Assessments

  • Using Tiles to Measure Students use color tiles to measure the lengths of two figures shown on the accompanying worksheet.
  • Using Paper Clips to Measure Students use paper clips to measure the length of two pictured items.
  • Using Cubes to Measure Height Students determine their heights determined by cutting a length of string to show this measurement. Then using snap cubes they measure the length of the string. Note: The measurement of the string will extend past 20 units, use this task with students who demonstrate a readiness to go beyond the measurement of 20 units.
  • Measuring the Width and Height of a Book Students are asked to use cubes to determine the length of different sized edges of a book.
  • Measure With Paper Clips Students measure the length of an unsharpened pencil with paper clips.
  • Measure With Color Tiles Students use color tiles to measure the length of rectangles.

Lesson Plans

  • Measuring End to End is a Win-Win! Be a winner at measuring length by learning how to measure from end to end! Students will learn where the first end and the last end are on an object. They will learn about lining up multiple copies of a non-standard measurement unit, with no gaps or overlaps, from end to end along the length of the object being measured and expressing the object’s length as the number of non-standard measurement units needed.
  • Measuring Madness After sharing the story Measuring Penny by Loreen Leedy, students will be excited to learn how to measure with nonstandard measuring tools. Your students will want to measure everything in the classroom!
  • "How Long is Your Train?" This lesson is intended to allow students to gain insight into the importance of measurement. The focus is on using non-standard units to measure the length of a "train" they create. Students are then required to compare the length of their train with a buddy's train.
  • Around the Room Measuring In this lesson, students practice measuring length using non-standard units of measurement.
  • Fishy Lengths - Which fish is right for my aquarium? Students explore lengths of fish to determine if fish are too long to fit in different sized aquariums. Students will use non-standard units and measuring tools to compare the lengths of fish and boxes without being able to directly hold the fish near the boxes.
  • How Big is a Dinosaur? In this dinosaur-themed lesson, students will use dinosaur manipulatives (and the teacher will demonstrate using a longer dinosaur footprint print-out) as units for nonstandard measurement of length. Students will use length comparison statements.

Tutorial

  • Measuring Length With No Gaps or Overlaps In this video tutorial from Khan Academy, called, "Measuring a golden statue", we see an example of how to solve a problem in which we measure an object with same-size length units that span it with no gaps or overlaps.
