K.1.1B More/Less, Compare & Order
Overview
All Standard Benchmarks  with codes
K.1.1.1 Recognize that a number can be used to represent how many objects are in a set or to represent the position of an object in a sequence.
K.1.1.2 Read, write, and represent whole numbers from 0 to at least 31. Representations may include numerals, pictures, real objects and picture graphs, spoken words, and manipulatives such as connecting cubes.
K.1.1.3 Count, with and without objects, forward and backward to at least 20.
K.1.1.4 Find a number that is 1 more or 1 less than a given number.
K.1.1.5 Compare and order whole numbers, with and without objects, from 0 to 20.
Essential Understandings
Developing an understanding of numbers, ways of representing numbers, and relationships among numbers is essential for Kindergarten students.
Research suggests that children learn number word sequences, the reading of numerals and the concept of quantity separately even though they are connected in instructional activities. Counting means so much more than reciting the words and writing the numerals for the counting sequence: 1, 2, 3, 4, ... When successfully counting a group of objects, children give a unique number name to each object (onetoone correspondence) and then recognize that the last number represents the quantity of objects in the group (cardinality). In addition, they will also successfully show a group of objects to represent a given number (up to 31).
Kindergartners expand their conceptual understanding of counting to include the idea that, when counting, the next number name refers to a quantity that is one larger. This understanding leads to the comparing and ordering of numbers with and without objects.
Kindergartners will use multiple representations to represent numbers. These representations include spoken words, numerals, pictures, real objects and manipulatives.
Benchmark K1.1.4
Find a number that is 1 more or 1 less than a given number.
Benchmark K1.1.5
Compare and order whole numbers, with and without objects, from 0 to 20.
What students should know and be able to do [at a mastery level] related to these benchmarks:
 use matching or counting strategies to identify whether the number of objects in one set is greater than, less than, or equal to the number of objects in another set.
 find a number that is one more or one less than a given number without counting from one. If asked, "What is one more than 7?" A kindergartner should respond 8 automatically without having to count 1,2,3...6,7...so 8.
 compare and order numbers from 0 20 with and without objects
 use the language of more than, greater than, as many as, less/ than, fewer than when comparing numbers.
Work from previous grades that supports this new learning includes:
 counting objects.
 representing the number in a group or set with a numeral.
 an intuitive sense of more and less. They can pick out the big truck and the small truck. They also know that they would rather have 3 cookies, than just 1.
 arranging and ordering things in their world.
NCTM Standards
Understand numbers, ways of representing numbers, relationships among numbers, and number systems
PreK2 Expectations:
 count with understanding and recognize "how many" in sets of objects;
 use multiple models to develop initial understandings of place value and the baseten number system;
 develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections;
 develop a sense of whole numbers and represent and use them in flexible ways, including relating, composing, and decomposing numbers;
 connect number words and numerals to the quantities they represent, using various physical models and representations;
 understand and represent commonly used fractions, such as 1/4, 1/3, 1/2.
Common Core State Standards
Know number names and the count sequence.
K.CC.1. Count to 100 by ones and by tens.
K.CC.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1).

Misconceptions
Student Misconceptions and Common Errors:
Students may think...
 less and more mean the same thing.
 they only have to use one digit when ordering twodigit numbers.
 that a set of three large objects is more than a set of three small objects.
Vignette
In the Classroom
More
The game of More is a simple card game like the game of War. Kindergarten students play in pairs using a deck of playing cards, 110 (ace equals one). It is important the cards have objects, representing the numeral, that can be touched and counted. Cups labeled with the numbers 110 will also be used to hold cards already played.
In this vignette, Ms. Burkhardt is facilitating a game with Susie and Julia while assessing their understanding of quantity and the concepts of more and less. This partner game was previously introduced to the class.
Ms. Burkhardt deals out all the cards face down to Julia and Susie. The girls have their cards in front of them.
Ms. Burkhardt: Julia, you turn over a card, and Susie, you do too. Then we will see which is more. Julia turns over a six of clubs and Susie turns over a five of hearts.
Ms. Burkhardt: Which is more?
Both girls: Six.
Ms. Burkhardt: How do you know that six is more than five?
Susie uses the fingers on one hand to show five. After she matches her five fingers to the clubs, she explains there is one extra club. Julia agrees and explains, "When you count you go past five to get to six. One, two, three, four, five, six. So six is more."
Ms. Burkhardt : Yes, six is more than five. I am going to place both (five and six) cards in the cup labeled six since six was the largest number.
Julia then turns over a ten of diamonds.
Before Susie can turn over her card, Ms. Burkhardt asks, "Susie, do you think you have a card that will be more than 10?"
Julia: No, because ten is the biggest in all the cards.
Susie: I think.........maybe????
Even though Susie knows only the cards 110 are included in the game she has not related this information to the magnitude of the numbers being compared. Ms. Burkhardt uses this opportunity to help Susie relate each of the numbers 19 to 10.
Ms. Burkhardt: What cards are we using for the game?
Susie says, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 as Ms. Burkhardt writes the numbers on the board.
Ms. Burkhardt: Is one is more than ten?
Susie: No.
Ms. Burkhardt: Is two more than 10?
Susie: No.
This continues until all numbers have been compared to ten.
Mrs. Burkhardt: Susie, are any of the numbers we are using in the game more than ten?
Susie: No, ten is the biggest.
Ms. Burkhardt: Is ten always the largest number when we play games?
Julia: No, just in this game because it is the largest of 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.
That's all the cards in the game.
Susie then turns over a six of diamonds and says, "Ten is more than six."
Ms. Burkhardt places both cards in the cup labeled 10.
Once all the cards have been played the contents in the cups are examined to review the concept of more. In the ten cup were ten and six, ten and four, ten and two, and ten and five. After looking at each pair of cards, the girls reiterated that ten is more than six, ten is more than four, etc.
Susie: Hey, the one cup has no cards!
Julia: Because one is the littlest. It can't beat anybody.
Julia: (continues exploring the cups) The four cup doesn't have any cards either.
Ms. Burkhardt: Could it?
Julia: It could have because four is more than three.
Susie: And two and one! How come it doesn't? She looks in the other cups.
Susie: Oh, look. Here's a four. It's in the five cup.
Julia: I get it, five is more than four. I think all the fours are with bigger numbers than four.
Susie: "Next time, the fours might be with other numbers."
Note: Kindergartners could use number cards for the game but would need access to objects in order to represent the numbers if they were unsure of which was more. This game can be varied to focus on the concept of less.

Resources
 Students may need support in further development of previously studied concepts and skills.
 The concept of less tends to be more difficult for kindergartners than the concept of more. When asking "Which is more?" questions, immediately follow with "Which is less?" in order to make connections from a less familiar term and concept to a better known idea.
 Kindergartners may be using the words "greater than" and "less than" but are not using the symbols < and >.
 It is easier for Kindergartners to order cards with numbers on them than to order numbers written on a single sheet of paper. The physical act of moving number cards allows them to easily rearrange when order numbers.
 Kindergartners need to order numbers using a number path. The numbers 0, 5 and 10 become benchmark numbers for Kindergartners. When using a number path, students are asked to determine where a particular number belongs rather than just filling in the numbers in counting order. For example, Where does the number 4 go on this number path? Does the number 3 belong in this space (pointing to the empty space next to 0)? The relationship of the numbers 1, 2, 3, 4, to 0 and 5 is highlighted when Kindergartners have to order them on the following number path:
0 



 5 
Kindergartners should also order numbers on a number path from 0 to 10
0

 Good questions, and good listening, will help children make sense of the mathematics, build selfconfidence 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."

"Vocabulary literally is the
key tool for thinking."
Ruby Payne
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 Multiple and varied opportunities to use the words in context. These
Use: 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 nonexamples.
Example/Nonexample 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
Performance Assessment Tasks
1. Ordering Numbers
Randomly place number cards (cards from 1 to 10) on the table.
Direct the student to arrange cards left to right in increasing order.
"Now say the numbers as you point to them."
(Similarly order the cards from 11 to 15 and 16 to 20.)
Solution, Part 1: 1,2,3,4,5,6,7,8,9,10 and names them correctly
Benchmark: K.1.1.5
2. Ordering Numbers
Using number cards (020), lay three cards in front of the student. Ask the
student to put the cards in order from the least to the greatest or greatest to least.
Solution: student orders numbers correctly
Benchmark: K.1.1.5
3. Compare Numbers
Using number cards (020), lay the numbers 5, 2, and 9 in front of the student. Ask, "Which number is the largest? How do you know? Which number is the smallest? How do you know?" Continue with other numbers such as, 13, 20, and 12.

Solution: one more and one less than given number
Benchmark: K.1.1.4
Differentiation
Students will need to use objects along with number cards when determining more and less. When physical models of numbers are used it is easier to match the objects in order to compare them. Use the language of more and less throughout these experiences.
Finding one or one less than a number is easily illustrated when using objects. Use the language of one more and one less throughout these related activities.
Concrete  Representational  Abstract Instructional Approach
(Adapted from The Access Center: Improving Access for All K8 Students)
The ConcreteRepresentationalAbstract Instructional Approach (CRA) is a researchbased 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 ontask. 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.

Develop the language of more and less as students work with objects representing numbers. These objects can then be matched to help differentiate between the set with more and the set with less.
Finding one or one less than a number is easily illustrated when using objects. Use the language of one more and one less throughout these related activities.
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.
 Word banks need to be part of the student learning environment in every mathematics unit of study.
 Use vocabulary graphic organizers such as the Frayer model (see below) to emphasize vocabulary words count, first, second, third, etc.
 ELL students need to see visual models with the numeral, word and quantity represented. By displaying visual models with the three aspects of number, they will make relationships between the numeral, word and quantity, rather than viewing them as three separate and different concepts.
 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:
7 is one more than _____________. 
5 is one less than ______________. 
__________ is one more than _____________. 
__________ one less than ______________.

Help Your Children Make Sense of Math
Ask the right questions
In helping children learn, one goal is to assist children in becoming critical and independent thinkers. You can help by asking questions that guide, without telling them what to do.
Good questions, and good listening, will help children make sense of the mathematics, build selfconfidence 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."
Getting Started
What do you need to find out?
What do you know now? How can you get the information? Where can you begin?
What terms do you understand/not understand?
What similar problems have you solved that would help?
While Working
How can you organize the information?
Can you make a drawing (model) to explain your thinking? What are other possibilities?
What would happen if . . . ?
Can you describe an approach (strategy) you can use to solve this?
What do you need to do next?
Do you see any patterns or relationships that will help you solve this?
How does this relate to ...?
Can you make a prediction?
Why did you...?
What assumptions are you making?
Reflecting about the Solution
How do you know your solution (conclusion) is reasonable? How did you arrive at your answer?
How can you convince me your answer makes sense?
What did you try that did not work?
Has the question been answered?
Can the explanation be made clearer?
Responding (helps clarify and extend their thinking)
Tell me more.
Can you explain it in a different way?
Is there another possibility or strategy that would work?
Is there a more efficient strategy?

Activities:
● Using a deck of cards (all face cards removed) and a collection of pennies, flip a card and have your child count out the same number of pennies as the card shows. Later, have your child count out 1 more or 1 less than the number on the card. Try with 2 more, 2 less, 3 more, 3 less.
● Write the numbers 020 on pieces of paper. Lay out 4 of the numbers. Have your child put the numbers in order from smallest to largest. Ask questions such as: How did you know which was the smallest? Biggest?
