About these worksheets
Function machine worksheets develop input-output reasoning skills. Students figure out the rule a function machine uses — whether addition, subtraction, multiplication, division, or a two-step operation — by analyzing input-output pairs, then apply the rule to find missing values. Resources span third through sixth grade.

- Figure out what number is being added or subtracted to turn each input into the output.
- Use a few input-output examples to spot a consistent pattern and name the rule.
- Check that the same rule works for every pair in the table before choosing an answer.
- Tell the difference between an “add” rule and a “subtract” rule by comparing inputs and outputs.

- Use a few input-output examples to spot a consistent pattern and write the rule.
- Check that the rule works by testing it on another input-output pair.
6rp3a
- Figure out the missing input or output number when a machine adds, subtracts, multiplies, or divides by a rule.
- Use the given input-output pairs to identify the operation and number being used in the rule.
- Work backward through an operation to find an unknown value (like undoing +, −, ×, or ÷).
- Check that a rule works for more than one pair in the table before filling in the blank.
- Figure out what number is being added or subtracted by looking at an input and its output.
- Use addition and subtraction facts within 50 to check which rule makes the outputs match.
- Choose the correct rule from a few options by testing it on the numbers shown.
- Figure out what a function machine is doing by looking at the input and output numbers.
- Use addition and subtraction to find the rule that changes one number into another.
- Figure out what a function machine is doing by looking at the input and output numbers.
- Use addition and subtraction to find the rule that changes one number into another.
- Figure out the rule that changes an input number into an output number using a letter like x or n.
- Use two-step rules that mix operations like add/subtract and multiply/divide.
- Check that a rule works by plugging in different inputs and seeing if you get the matching outputs.
