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

In a Nutshell

Students must be able to talk about objects and compare them. Students need to be comfortable 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 as students compare various objects in order to determine longest/shortest, heaviest/lightest, tallest/shortest, etc. Develop accurate and appropriate procedural fluency as they measure various objects for length, height, size, weight, etc.	Focus learning by introducing and modeling comparative vocabulary. Build conceptual understanding by providing multiple opportunities for students to compare objects. Facilitate meaningful discourse by encouraging students to explain their thinking using comparative words such as longest/shortest, biggest/smallest, heaviest/ lightest in/out, etc.
