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.

Lesson Plans

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.

Type: Lesson Plan

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.

Type: Lesson Plan

Trains and Towers:

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

Type: Lesson Plan

Moving on Up:

This MEA lesson is designed for a Kindergarten grade level. 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 and they will learn about weight by differentiating between heavy items and lighter items. The students will be using criteria such as pricing, moving of vehicles, speed, safety and overall rating.

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. Click here to learn more about MEAs and how they can transform your classroom.

Type: Lesson Plan

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.

Type: Lesson Plan

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.

Type: Lesson Plan

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.

Type: Lesson Plan

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.

Type: Teaching Idea

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.

Type: Teaching Idea

Virtual Manipulative

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.
