Georgia K.MDR.7

K.MDR.7 is a Georgia mathematics standard. These are the expectations under it.

• K.MDR.7.1

  Directly compare, describe, and order common objects, using measurable attributes (length, height, width, or weight) and describe the difference.

• K.MDR.7.2

  Classify and sort up to ten objects into categories by an attribute; count the number of objects in each category and sort the categories by count.

• K.MDR.7.3

  Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.

01

What Students Need to Do

Students notice features such as color, shape, texture, length, height, and weight. They compare objects and read simple graphs to answer questions about groups and amounts.

02

What Mastery Looks Like

Students describe objects with clear attribute words and compare two objects accurately. They count graph symbols and answer questions about how many, more, fewer, most, and least.

03

Common Misconceptions

Students may use bigger when they mean longer, taller, or heavier. They may think an object’s position changes its length. On graphs, they may count symbols incorrectly or confuse most with least.

04

How to Assess It

Give students two paper strips and a picture graph. Ask them to circle the longer strip, then identify which graph category has more and explain how they know.

1. 01

   Give pairs a tray of classroom objects to sort, compare by length or weight, and record each group with connecting cubes.

2. 02

   Show two objects and ask, “How are they alike, how are they different, and which is longer?” Students draw or dictate answers.

3. 03

   Play Attribute Hunt by calling clues such as round, shorter than a pencil, or heavier than an eraser for students to match.

4. 04

   Graph students’ daily transportation choices with sticky notes, then ask which choice has the most, least, or same number.

• 5.MDR.7.2

  Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.

• 4.MDR.6

  Measure time and objects that exist in the world to solve real-life, mathematical problems and analyze graphical displays of data to answer relevant questions.

• 5.MDR.7

  Solve problems involving customary measurements, metric measurements, and time and analyze graphical displays of data to answer relevant questions.
