Georgia K.MDR.7.1
The Standard
Directly compare, describe, and order common objects, using measurable attributes (length, height, width, or weight) and describe the difference.
Georgia's K-12 Mathematics Standards · Observe, describe, and compare the physical and measurable attributes of objects and analyze graphical displays of data to answer relevant questions.

What This Standard Means
What Students Need to Do
- Students compare objects using one chosen feature, such as length, height, width, or weight. They put objects in order and tell how one differs from another.
What Mastery Looks Like
- A student lines up objects at the same starting point or holds them to compare weight. The student orders three objects and uses words such as longer, shorter, taller, wider, heavier, or lighter correctly.
Common Misconceptions
- Students may think the object that looks bigger is always longer or heavier. They may compare from uneven starting points or confuse height with length. Some reverse words such as heavier and lighter.
How to Assess It
- Give each student three classroom objects. Ask them to order the objects by length, then explain how they checked and describe one difference.

Ways to Teach It
Have students line up pencils, crayons, and markers at one edge, then order them from shortest to longest.
Show two classroom objects and ask, "Which attribute should we compare, and what words describe the difference?"
Play Compare and Place, where students draw object cards and place each item in order by length, height, width, or weight.
Compare grocery items by holding them, then discuss why package size does not always tell which item is heavier.
