MA.K.M.1.2

Directly compare two objects that have an attribute which can be measured in common. Express the comparison using language to describe the difference.

Clarifications

Clarification 1: To directly compare length, objects are placed next to each other with one end of each object lined up to determine which one is longer.

Clarification 2: Language to compare length includes short, shorter, long, longer, tall, taller, high or higher. Language to compare volume includes has more, has less, holds more, holds less, more full, less full, full, empty, takes up more space or takes up less space. Language to compare weight includes heavy, heavier, light, lighter, weighs more or weighs less.

Lesson Plans

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.

Balancing Equations:

This is an engaging, hands-on lesson to help the students understand the meaning of the equal sign. The lesson is written using a pan/equal arm balance but may be done with just connecting cubes.

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.
