K.GM.2.1

K.GM.2.1 Use words to compare objects according to length, size, weight, position, and location.

In a Nutshell

This objective helps students build their mathematical vocabulary and ability to compare. Through daily conversation in their centers and lessons, students should be able to talk about objects and compare them. Students will be exposed to and become comfortable with using words such as longer, shorter, bigger, smaller, heavier, lighter, next to, under, on, etc.

Student Actions	Teacher Actions
Communicate mathematically by using words to compare two objects by length, size, weight, position, or location. Develop mathematical reasoning by comparing various objects in order to determine longest/shortest, heaviest/lightest, tallest/shortest, etc.	Focus learning by introducing, modeling, and encouraging comparative vocabulary. Build conceptual understanding by providing multiple opportunities for students to compare objects and discuss in groups. Facilitate meaningful discourse by encouraging students to explain their thinking using comparative words such as longest/shortest, biggest/smallest, heaviest/ lightest in/out, etc.
Key Understandings	Misconceptions
Words can be used to compare objects (comparative vocabulary). Basic knowledge of length, size, weight, position, and location.	Misuse of vocabulary (bigger means heavier, smaller means lighter, etc.)
Knowledge Connections
Prior Knowledge	Leads to
Identify measurable attributes of objects. Describe them as little, big, long, short, tall, heavy, light, or other age-appropriate vocabularies. (PK.GM.2.1)	Use nonstandard and standard measuring tools to measure the length of objects to reinforce the continuous nature of linear measurement (1.GM.2.1)
