Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.


General Information

Subject Area: Mathematics
Grade: K
Domain-Subdomain: Measurement and Data
Cluster: Level 2: Basic Application of Skills & Concepts
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

Name Description
Taller or Shorter

Students compare their heights to that of a partner and describe the difference in their heights.

Longer Than

Students are asked to compare the lengths of their arms to items around the classroom.

Compare Two Bags

Students compare the weights of two sandwich bags, one containing cotton balls and one containing rice.

Compare Lengths of Cubes

Students compare the lengths of two trains of cubes and are assessed in order to determine if they understand conservation of length.

Comparing Lengths

Students are asked to compare the lengths of two pieces of string.

Lesson Plans

Name Description
Kindergarten 5 Senses with Pumpkins

This unit opens with a field trip to the pumpkin patch. In this project-based learning experience students will use their five senses to discover the world around them. Students will complete a KWL chart, pumpkin chart, and have group discussions. Individually students will use their five senses to describe the taste, touch, smell, look, and sound of different objects. As teams, students will create a poster to present their findings.

Short or Tall? Compare Them All!

In this lesson, students will use the measurement language 'taller' and 'shorter' to compare their height to another classmate and to the heights of items in the classroom.

Trains and Towers

During this lesson students will learn to directly compare the length of objects. While building structures with connecting cubes the students will participate in collaborative conversations with a partner. This will allow students to use comparison language such as longer, taller, and shorter.

Moving on Up

In this Model Eliciting Activity, MEA, students will be working in small groups to figure out what moving company is best for a family that is moving to a different state. The students will be using criteria such as pricing, moving of vehicles, speed, and safety.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

Tightrope!

In this lesson, students will practice measuring items within the classroom to explore differences in length. The teacher will give a specific measurement size for the students to match with common classroom objects to explore longer and shorter lengths.

Weight a Minute!

This lesson uses an "I do, We do, You do" approach to comparing and describing objects using weight. The students will use manipulatives to investigate and compare the weight of given objects. This lesson covers only one attribute of the standard. This lesson is a great way to get students involved in their learning and to help foster a love of math. Included in the lesson is a formative and summative assessment to help monitor the students' progress and understanding of the lesson.

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.

The Long and Short of Candy {Exploring Measurement}

In this lesson, students will describe and compare measurable attributes of candy bars as well as work to find objects that are longer than and shorter than a specified object.

A-Weigh We Go!

Using different items available at home (e.g., bag of flour, box of detergent) students are estimating, measuring and comparing the weight of these items. They examine if "bigger" also means "heavier" and try to find out how to weigh an object that is too big for a bathroom scale.

Virtual Manipulative

Name Description
Long or Short?

This is an interactive game where students are prompted to distinguish between a longer or shorter object. The tool increases in difficulty as the student progresses.
