Input and Output Function Tables Worksheets

Before you learn how to answer questions about function tables you need to know what they are and how they work.

Input and Output tables are the same thing as function tables.

Function tables consist of three parts, one of which is usually missing:

• an input which is usually a number
• a rule or function
• an output which is another number

The input is acted on by the rule or function to create the output.

If you want to find out more about these types of tables before you start answering questions, then take a look at our support page.

Before we introduce out input output tables worksheets, you need some background information about the types of question you might get!

Function table (Input and Output Table) questions fall into 3 different categories:

• finding the output if we know the input and the rule (or function).
• finding the input if we know the output and the rule (or function).
• finding the rule or function if both the inputs and outputs are known.

We have created a range of different worksheets for you to practice all these skills.

We have split these worksheets into 5 different sections across two webpages.

• The first 3 sections are at an easier level and involve working with input and output tables with rules rather than algebraic functions. You will find these worksheets here.
• The last 2 sections, which are harder, are on this page and involve working with algebraic functions.

Within each section, the sheets get gradually harder.

We also have an quiz at the bottom of the page where you can practice your input output tables online.

These function table worksheets start off with linear functions with one rule and the questions get gradually harder.

• Sheets 4A involves finding the output when the input and rules are known
• Sheet 4B involves finding the input or output when the rule is known
• Sheet 4C involves finding the rule when the inputs and outputs are known. The inputs increase by 1 each time to make it easier to find the rule.
• Sheet 4D involves finding the rule when the inputs and outputs are known. The inputs are randomly chosen to make it harder to work out the rule.

The rules in this section are all single operation rules.

These worksheets involve finding the missing outputs, inputs and the missing rule in the function tables with both linear and non-linear functions.

The rules in this section are all single operation rules.

• Sheet 5A involves finding the missing outputs when the input and the rule are known.
• Sheet 5B involves finding the missing inputs and outputs when the rule is known.
• Sheet 5C involves finding the missing rules when the inputs and outputs are known. The inputs are increasing by 1 each time to make it easier to find the rule.

Here are our easier input and output tables worksheets.

These sheets start at a basic level and involve using rules rather than algebraic equations.

They are suitable for 3rd grade and up.

We have created a support page to help you to answer a range of questions involving function tables.

Each of the three different types of question above are included in our worked examples which are solved step-by-step.

If you are finding the questions on the sheets here tricky, this should help you!

If you are looking for some 6th grade algebra worksheets to use with your child to help them understand simple equations then try our selection of basic algebra worksheets.

There are a range of 6th grade math worksheets covering the following concepts:

• Generate the algebra - and write your own algebraic expressions;
• Calculate the algebra - work out the value of different expressions;
• Solve the algebra - find the value of the term in the equation.
• Use the distributive property to factorize and expand different expressions

This online input output tables quiz tests your knowledge and skill at generating and finding the missing inputs, outputs and functions for a range of function tables.

The link below will open the quiz in a dedicated quiz page or you can preview a copy of the quiz underneath.

The Math Salamanders hope you enjoy using these free printable Math worksheets and all our other Math games and resources.
