K.3.2 Measurement Ideas
Use words to compare objects according to length, size, weight and position.
For example: Use same, lighter, longer, above, between and next to.
Another example: Identify objects that are near your desk and objects that are in front of it. Explain why there may be some objects in both groups.
Order 2 or 3 objects using measurable attributes, such as length and weight.
Overview
K.3.2 Essential Understandings
Measurement is one of the most widely used applications of mathematics. Kindergarten students develop measurement concepts as they directly compare objects using the attributes of length, weight, size, and position. They order two or more objects using the attributes of length, weight and size. Kindergartners use the words above, below, next to, and between to describe the relative position of an object.
All Standard Benchmarks
K.3.2.1 Use words to compare objects according to length, size, weight and position.
K.3.2.2 Order 2 or 3 objects using measurable attributes, such as length and weight.
Benchmark Group A
K.3.2.1 Use words to compare objects according to length, size, weight and position.
K.3.2.2 Order 2 or 3 objects using measurable attributes, such as length and weight.
What students should know and be able to do [at a mastery level] related to these benchmarks:
- Use words such as shorter, longer/taller, and about the same to compare the length of objects. Use this knowledge to order two or more objects according to length.
- Use words such as larger, smaller, and about the same to compare the size of objects. Use this knowledge to order two or more objects according to size.
- Use words such as heavier, lighter, and about the same to compare weight of objects. Use this knowledge to order two or more objects according to weight.
- Describe the relative position of an object using above, below, between and next to.
Work from previous grades that supports this new learning includes:
- Young children have a natural curiosity about people and things in their world. This curiosity leads to finding out how things are related or how they fit together.
NCTM Standards
Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships.
PreK-2 Expectations
- Recognize, name, build, draw, compare, and sort two- and three-dimensional shapes.
- Describe attributes and parts of two- and three-dimensional shapes.
- Investigate and predict the results of putting together and taking apart two- and three-dimensional shapes.
Common Core State Standards:
Describe and compare measurable attributes.
- K.MD.1. Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
- K.MD.2. Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
Classify objects and count the number of objects in each category.
- K.MD.3. Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
Misconceptions
Students may think...
- large objects weigh more.
- the length of an object changes when its position is changed.
- words used to describe relative position are interchangeable.

In the Classroom
Vignette
The students in Mr. R.'s class are describing differences as they directly compare people and objects.
Mr. R: Today we are going to figure out how things are different.
Would someone like to help with this activity?
Reid, will you come to the front of the room?
Reid walked up and stood beside Mr. R.
Mr. R: How are Reid and I different?
Connor: You are a lot bigger, Mr. R!
Mr. R: What do you think Connor means when he says I am a lot bigger than Reid?
Annie: I think it means you're older than Reid.
Connor: No...it's not about old. Mr. Reid is bigger!
Mr. R.: Let's think about this class. Could bigger mean older? taller? longer? Talk to your Math Talk Partner about this question.
Mr. R. listened as the students shared with their partners. Most students focused on the "taller" but a pair started to compare the size of their feet. A few students stood and compared their heights.
Mr. R.: When does bigger mean older?
Josiah: My big sister is older than me.
Mr. R.: When does bigger mean longer?
Xiong: Mr. R., your feet are bigger than my feet. That means they are longer. A lot longer!!
Mr. R.: When does bigger mean taller?
Connor: Oh....I mean you are taller. I said you were bigger than Reid but you are taller than Reid.
Mr. R.: When you compare how tall Reid and I are you are talking about our heights.
Mr. R.: Think again about our heights-how tall we are. Can someone use another word to compare our heights?
Amanda: Reid is not taller, Mr. R. You are.
Mr. R.: Is there another way we can say that Reid is not taller than Mr. R.?
Carson: Reid is shorter than you, Mr. R.
Mr. R.: Yes, Reid is shorter than Mr. R. and Mr. R. is taller than Reid. We are comparing our heights and finding out who is taller and who is shorter.
Mr. R. writes the following on the board:
Mr. R. is taller than Reid.
Reid is shorter than Mr. R.
Mr. R. reads the sentences one at a time and asks the students to repeat them.
Mr. R. now pairs students and asks them to find out who is taller and who is shorter. He moves from pair to pair asking, Who is taller? Who is shorter? and How do you know? He works with students to use the language of comparison. __________ is taller than________. _________ is shorter than __________. I am taller than _______. I am shorter than _______. __________ is taller than me. ___________ is shorter than me.
The students in Mr. R.'s class directly compared people according to the attribute of height. Students' natural language did not convey the relationship between the height of Reid and Mr. R. Mr. R. asked questions and elicited responses that would appropriately describe the height of one person as it related to the height of another person. This scenario will be repeated many times as these kindergartners directly compare length, size and weight of objects. Once students understand the process and language of comparisons of height, size, length and weight they will directly compare more than two objects.
For example, a child might compare these pencils.
Ross: First I found the longest and the shortest. Then I put this one in the middle. It is not the longest or the shortest. It goes in between.

Teacher Notes
- Students may need support in further development of previously studied concepts and skills.
- Kindergartners should sort objects into groups based on a comparison to a known object. For example, using a pencil as a referent, students would sort objects into three groups--longer than the pencil, shorter than the pencil, and about the same length as the pencil.
- Kindergarten students need to compare/order real objects rather than pictures on paper.
- Students should be asked to compare lengths of non-rigid objects including pieces of yarn or jump ropes.
- Students need to compare the weights of large, light objects and small heavy objects.
- Asking students to compare the weight of objects they cannot see keeps the focus on the attribute of weight rather than on the size of the object. Placing objects of differing weights in covered boxes, closed paper bags or in socks, enables young children to compare the weight without identifying the object.
- Good questions, and good listening, will help children make sense of the mathematics, build self-confidence and encourage mathematical thinking and communication. A good question opens up a problem and supports different ways of thinking about it. The best questions are those that cannot be answered with a "yes" or a "no."

Additional Instructional Activities
Longer, Shorter, About the Same
Students sort objects as longer, shorter, or about the same as a reference object. The reference object can be changed to produce different sorts. Students could also put objects in order from shortest to longest. This activity can be modified to a different measurement such as weight or size. Consider using objects such as straws, pieces of string, strips of paper, etc.
Measurement Hunt
Students use a reference object (strip of paper, straw, piece of string) to find objects in the room. One day, students may hunt for 6 objects that are longer than their reference object. The next day, they might hunt for objects that are shorter or about the same length as their reference object. Students can record their measurements by drawing pictures or writing the name of the objects they found on the measurement hunt. This activity could be modified to address the measurement areas of weight and general size.

Mathematics vocabulary words describe mathematical relationships and concepts and cannot be understood by simply practicing definitions. Students need to have experiences communicating ideas using these words to explain, support, and justify their thinking.
Learning vocabulary in the mathematics classroom is contingent upon the following:
Integration: Connecting new vocabulary to prior knowledge and previously learned vocabulary. The brain seeks connections and ways to make meaning which occurs when accessing prior knowledge.
Repetition: Using the word or concept many times during the learning process and connecting the word or concept with its meaning. The role of the teacher is to provide experiences that will guarantee connections are made between mathematical concepts, relationships, and corresponding vocabulary words.
Meaningful Use: Multiple and varied opportunities to use the words in context. These opportunities occur when students explain their thinking, ask clarifying questions, write about mathematics, and think aloud when solving problems. Teachers should be constantly probing student thinking in order to determine if students are connecting mathematics concepts and relationships with appropriate mathematics vocabulary.
Strategies for vocabulary development
Students do not learn vocabulary words by memorizing and practicing definitions. The following strategies keep vocabulary visible and accessible during instruction.
Mathematics Word Bank: Each unit of study should have word banks visible during instruction. Words and corresponding definitions are added to the word bank as the need arises. Students refer to word banks when communicating mathematical ideas which leads to greater understanding and application of words in context.
Labeled pictures and charts: Diagrams that are labeled provide opportunities for students to anchor their thinking as they develop conceptual understanding and increase opportunities for student learning.
Frayer Model: The Frayer Model connects words, definitions, examples and non-examples.
Example/Non-example Charts: This graphic organizer allows students to reason about mathematical relationships as they develop conceptual understanding of mathematics vocabulary words. Teachers should use these during the instructional process to engage student in thinking about the meaning of words.
Vocabulary Strips: Vocabulary strips give students a way to organize critical information about mathematics vocabulary words.
word | definition | illustration |
Encouraging students to verbalize thinking by drawing, talking, and writing increases opportunities to use the mathematics vocabulary words in context.

Assessment
- Using boxes or socks filled with objects of varying weights, students select two, then compare and describe the weight of each. Students may be prompted with the following questions: Are they the same weight? Is one heavier? Is one lighter?
Solution: Correctly identifies the heaviest or the lightest.
Benchmark: K.3.2.1
- Comparing Length
Materials: a box of familiar objects such as pencils, toothbrushes, forks, spoons, crayons, paint brushes, etc.
Instructions: After drawing draw two items from the box, students compare and then describe the length of the objects. Students may be prompted with the following questions: Are they the same length? Is one shorter? Is one longer?
The activity can be repeated using weight as the measurable attribute.
Solution:
Benchmark: K.3.2.1
- Ordering
Students are given sets of objects to order according to length (shortest to longest or longest to shortest) or weight (lightest to heaviest or heaviest to lightest).
Solution: Correctly orders objects according to length or weight.
Benchmark: K.3.2.2
- Using Cuisenaire Rods, students pick 3 rods and order them from shortest to longest or longest to shortest.
Solution: Correctly orders rods from shortest to longest or longest to shortest.
Benchmark: K.3.2.2
Differentiation
Struggling learners should compare two objects to determine which is longer or larger before comparing and ordering three or more objects.
When comparing the weight of two objects the difference in weight should be obvious when the objects are held.
Concrete - Representational - Abstract Instructional Approach
Adapted from The Access Center: Improving Access for All K-8 Students
The Concrete-Representational-Abstract Instructional Approach (CRA) is a research-based instructional strategy that has proven effective in enhancing the mathematics performance of students who struggle with mathematics.
The CRA approach is based on three stages during the learning process:
Concrete - Representational - Abstract
The Concrete Stage is the doing stage. The concrete stage is the most critical in terms of developing conceptual understanding of mathematical skills and concepts. At this stage, teachers use manipulatives to model mathematical concepts. The physical act of touching and moving manipulatives enables students to experience the mathematical concept at a concrete level. Research shows that students who use concrete materials develop more precise and comprehensive mental representations, understand and apply mathematical concepts, and are more motivated and on-task. Manipulatives must be selected based upon connections to the mathematical concept and the students' developmental level.
The Representational Stage is the drawing stage. Mathematical concepts are represented using pictures or drawings of the manipulatives previously used at the Concrete Stage. Students move to this level after they have successfully used concrete materials to demonstrate conceptual understanding and solve problems. They are moving from a concrete level of understanding toward an abstract level of understanding when drawing or using pictures to represent their thinking. Students continue exploring the mathematical concept at this level while teachers are asking questions to elicit student thinking and understanding.
The Abstract Stage is the symbolic stage. Teachers model mathematical concepts using numbers and mathematical symbols. Operation symbols are used to represent addition, subtraction, multiplication and division. Some students may not make a clean transfer to this level. They will work with some symbols and some pictures as they build abstract understanding. Moving to the abstract level too quickly causes many student errors. Practice at the abstract level will not lead to increased understanding unless students have a foundation based upon concrete and pictorial representations.

English Language Learners need the vocabulary embedded as they compare objects. Identifying the attribute by which objects are being compared is critical as skills in language and measurement are being developed.
Serial ordering should be done with three objects in order to develop the language needed to describe ordering objects according to an attribute from least to greatest and greatest to least.
Words used to describe position need to be illustrated using physical objects that students can move.
Word banks need to be part of the student learning environment in every mathematics unit of study. Refer to these throughout instruction.
Use vocabulary graphic organizers such as the Frayer model (see below) to emphasize vocabulary words such as: bigger, larger, smaller, little, longer, shorter, taller heavier, lighter, next to, between, above, below, next to, etc.
- Sentence Frames
Math sentence frames provide support that English Language Learners need in order to fully participate in math discussions. Sentence frames provide appropriate sentence structure models, increase the likelihood of responses using content vocabulary, help students to conceptualize words and build confidence in English Language Learners.
Sample sentence frames related to these benchmarks:
_______________ is longer than _______________. |
__________________ is shorter than __________________. |
_________________ is heavier than _________________. |
I know this is the shortest because _________________________________. |
When assessing the math skills of an ELL student it is important to determine if the student has difficulty with the math concept or with the language used to describe the concept and conceptual understanding.
