This week we looked at function boxes. We began by exploring function boxes using a special function machine online. This machine took a number in, changed the number in some way, and spit the number back out as a new number. As we dumped numbers into the machine, we charted what they were going in and coming out as in order to find out what rule the function machine was following to change the numbers. Students did a great job figuring this out. Next, we decided the rule the machine would follow and then predicted what a given number would come out as after we put it into the machine. We also challenged ourselves to see if we could figure out what number went into the function machine if we knew what it came out as and what the rule was the machine was following!
To wrap up our activity, students came up with their own rule for the machine (they kept this a secret) and then came up with a list of numbers before they went into the machine and after they came out of the machine. Finally, they created their own function machine. See if you can figure out the rule their function machine is following!
