input/output table
Reading Passage 1
Using Rules in Input/Output Tables
An input/output table helps us see how numbers change. Each row shows two numbers: one is the input, and the other is the output. A rule tells us how to change the input into the output.
For example, if the rule is “add 3,” then 1 becomes 4, and 2 becomes 5. These pairs can be written as (1,4) and (2,5).
We can use input/output tables to find patterns in numbers. If we change the rule, the numbers change too. A bigger number makes the output grow faster. A smaller number makes it grow slower. These tables help us see and understand number patterns.
Reading Passage 2
Using Rules in Input/Output Tables
An input/output table is a tool that helps show how numbers change using a rule. Each row in the table shows a pair of numbers. The first number is the input, and the second is the output. A rule explains how the input changes to become the output.
For example, a rule might say “multiply by 2.” If the input is 3, the output would be 6. If the input is 4, the output would be 8. These pairs (3,6), (4,8) can help us find patterns.
Input/output tables help us practice using rules and number patterns. If we change the rule, the pattern changes. A rule like “add 5” grows more slowly than “multiply by 3.” These patterns help us understand how math works.
Reading Passage 3
Using Rules in Input/Output Tables
An input/output table organizes pairs of numbers that follow a specific rule. The input is the starting number, and the rule explains how to find the output. These tables are used to identify patterns, test number relationships, and make predictions.
For example, with the rule “multiply by 2,” the input 5 gives an output of 10. A set of these (2,4), (3,6), (5,10) shows how numbers grow based on the rule.
Changing the rule changes the pattern. Adding 2 creates a slower increase, while multiplying by 4 creates a steeper one. Exploring input/output tables helps us understand the behavior of numbers and how different rules produce different results.
