4.2.1 Input-Output Rules
Overview
Standard 4.2.1 Essential Understandings
Fourth graders further develop their understanding of a function as they work with input-output rules involving more than one operation. They create, complete and extend input-output tables. Fourth graders describe patterns in given input-output situations/tables and find a rule. Given a rule, fourth graders are able to find the output for a corresponding input and find an input for a corresponding output. They realize the value of the output varies depending on the value of the input. Fourth graders use input-output rules involving addition, subtraction and multiplication to solve problems in various contexts.
All Standard Benchmarks
4.2.1.1
Create and use input-output rules involving addition, subtraction, multiplication and division to solve problems in various contexts. Record the inputs and outputs in a chart or table.

Find the input when given an output and the rule.
- Use single-operation input-output rules to represent patterns and relationships and to solve real-world and mathematical problems.
NCTM Standards
Understand patterns, relations, and functions
Grades 3-5 Expectations:
- Describe, extend, and make generalizations about geometric and numeric patterns.
- Represent and analyze patterns and functions, using words tables, and graphs.
Represent and analyze mathematical situations and structures using algebraic symbols
Grades 3-5 Expectations:
- Identify such properties as commutativity, associativity, and distributivity and use them to compute with whole numbers.
- Represent the idea of a variable as an unknown quantity using a letter or a symbol.
- Express mathematical relationships using equations.

Common Core State Standards
Generate and analyze patterns.
4.OA.5. Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.
Misconceptions
Student Misconceptions and Common Errors
Students may think...
- the relationships between input values and the relationships between output values are the most important when trying to describe an input-output rule.
- an input-output rule can be determined using only one input-output pair.
Resources
Teacher Notes
- Students may need support in further development of previously studied concepts and skills.
- Students need to see input-output tables in both vertical and horizontal orientation.
- Use pattern blocks, toothpicks, square tiles, etc., to create growing patterns that can then be represented in an input-output table. Find the rule for the patterns.
For example,
- Students may have difficulty applying a given rule to generate a pattern due to computational errors rather than a failure to comprehend the rule.
- Students may have more difficulty finding rules for patterns that do not have a constant change.
- Students need to see and use input-output tables that do not have sequential inputs.
- Provide experiences with input-output tables that have gaps and/or unknowns in input and/or output columns.
- Emphasize the relationship between the input and output.
- Students should be able to prove that a "suggested rule"(incorrect rule) does not fit the input-output situation.
- Students should be able to describe rules in a variety ways.
- Multiple representations of input-output situations should include verbal descriptions, tables, equations, models or drawings.
- 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."

NCTM Illuminations
Using a context of chairs around square tables, students will be exposed to three different linear patterns in this lesson. The patterns vary slightly from situation to situation, and the third situation allows students to determine a solution in multiple ways, in the end leading to an intuitive understanding of perimeter.
Present the following situation to students:
At Pal-a-Table, a new restaurant in town, there are 24 square tables. One chair is placed on each side of a table. How many customers can be seated at this restaurant?
Show an arrangement of one table with four chairs. If your room contains large square tables at which students work in groups, use them as a demonstration. If not, you can draw a picture on the chalkboard, or you can use pattern blocks or other transparent manipulatives on the overhead projector.
When all students understand how chairs are placed, ask, "If there were 24 tables in a room, how many chairs would be needed?" Depending on students' understanding of multiplication, they may immediately realize that the answer is 24 × 4 = 96. If not, work with the class to complete a table, as follows:
Tables | Chairs |
1 | 4 |
2 | 8 |
3 | 12 |
4 | 16 |
5 | 20 |
From this table, students should realize that the number of chairs is equal to four times the number of tables. Alternatively, they might recognize that each time a table is added, four chairs are added. If there are some students who use each approach, this is a good opportunity to reinforce the connection between multiplication and repeated addition. That is,
2 × 4 | = | 4 + 4 |
3 × 4 | = | 4 + 4 + 4 |
4 × 4 | = | 4 + 4 + 4 + 4 |
5 × 4 | = | 4 + 4 + 4 + 4 + 4 |
and so on.
The following link provides a unit made up of 5 lessons:
lesson 1 explores patterns using pattern blocks and pattern core
lesson 2 explores multiplication and hundreds chart patterns
lesson 3 explores growing patterns and Pascal's Triangle
lesson 4 explores numeric patterns, Fibonacci numbers, and tables to organize information
lesson 5 explores creation, description, and analysis of patterns using tables and charts.

input-output table
"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 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
Solution: B
Benchmark: 4.2.1.1
MCA III item sampler
Performance Assessments (Adapted from Minnesota 2007 Mathematics Standards document examples):
- If the rule is "multiply by 3 and add 4," record the outputs for given inputs in a table.
Sample Answer:
X | Y |
0 | 4 |
1 | 7 |
2 | 1 |
Note: Differentiate by providing table and some cells, or requiring the use of specific values for X.
- A student is given these three arrangements of dots:
Identify a pattern that is consistent with these figures, create an input-output rule that describes the pattern, and use the rule to find the number of dots in the 10th figure.
Sample Answer:
Students may draw the next few figures and recognize that the number of dots is a multiplication problem where the rectangle has a side that is one more than the other side.
There are 10*11 = 110 dots in the tenth figure.
Benchmark: 4.2.1.1
Differentiation
- Use pattern blocks, tiles, and other manipulatives to create growing patterns that can be represented in an input-output table. Describing the relationship between inputs and outputs is important as fourth graders develop algebraic thinking.
For example,
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.

- Use pattern blocks, tiles, and other manipulatives to create growing patterns that can be represented in an input-output table. Describing the relationship between inputs and outputs is important as fourth graders develop algebraic thinking.
For example,
- Word banks need to be part of the student learning environment in every mathematics unit of study. Refer to these throughout instruction.
- Word Use vocabulary graphic organizers such as the Frayer model (see below) to emphasize vocabulary words count, first, second, third, 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:
If the input is _______________________ the output is __________________________. |
I know the rule is _________________ because ________________________________. |
If the output is __________________ the input was ______________________________. |
- 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.

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 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."
