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


General Information

Subject Area: Mathematics
Grade: 1
Domain-Subdomain: Measurement and Data
Cluster: Measure lengths indirectly and by iterating length units. (Major 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

Name Description
What’s The Length of the Third Set?

Students compare the lengths of two cube trains indirectly by using a third cube train.

The Missing Pencil

Students are asked to indirectly compare the lengths of three pencils based on the known lengths of two of the pencils.

Longest to Shortest Cubes

Students put three trains (sets of joined cubes) in order from longest to shortest.

Line Lengths

Students are asked determine which line is longer using cubes, string, a pencil, a ruler, or another measuring strategy.

Comparing Widths and Heights of Books

Students are asked to place three books in order from least to greatest bottom edge length and least to greatest side edge length.

Lesson Plans

Name Description
Thrice is Nice?

In this lesson, students will directly compare and order the length of three flowers and discuss the comparisons using comparison language.

What is in the Size of a Foot?

This lesson will allow students to compare and order the length of objects by using an item close to them... their feet! They will explore the length of their feet compared to the lengths of the feet of others in their groups. Students will then make statements to describe the comparison of the length of their feet, and other objects, using comparison language such as shorter, shortest, longer, and longest.

How Does Your Garden Grow?

In this lesson, students will help create an interactive bulletin board by measuring the height of a paper flower using connecting cubes and then directly comparing the height of their flower to the height of two others. Then students will "plant" their flowers in flowerpots on the bulletin board in order from shortest to tallest, so that other class gardeners will have the chance to see how they “grow”!

Teaching Ideas

Name Description
Arctic Paradise Measurement

In this activity, students use hands-on manipulatives to find the length and height of different arctic pictures using a nonstandard measurement unit: snowflakes. Students then use their data and order objects by length and height.

How Big is a Blue-SeaWorld Classroom Activity In this activity, given pictures of whales, the student will sort the whales by size. Given a rope marked with several whale lengths, the student will compare the lengths of these whales.
