Understanding how input and output work in function machines is a great way to learn about algebra in 7th-grade math.
Think of a function machine like a magical box. Here’s how it works:
Input: This is the number you put into the function machine. For example, let’s say you input the number 3.
Rule: The function machine has a rule it follows. This could be something like “add 5.”
Output: After using the rule on the input, you get the output. So if you input 3 and the rule is to add 5, the output will be .
Let’s say we have a function machine where the rule is “multiply by 2.” If the input is 4, here’s what happens:
This idea of input and output is similar to algebra. The rule works like an algebra operation. It helps you see patterns and create equations.
Why not make your own function machine? Choose a rule, pick some inputs, and see what outputs you get. This activity will help you understand functions better and prepare you for solving equations later on!
