4.7 based on 15 votes

In elementary math, a function machine is a diagram that contains an input that applies a math rule, like a set operation of addition or subtraction, to create an output, or the answer. This means that each graph contains various numbers for input and output, but they are tied together by a common rule. Essentially, children are examining the diagram for a common relationship between each input and output value. Use this vivid worksheet to help your child analyze the function machines to find the addition or subtraction rule that is being used for each!
