Function Machines: Find the Rule

Students will have fun with inputting numbers and checking the output numbers with this video worksheet!

Function machines help with student’s problem-solving skills and improve algebra skills. In this video, students have an input number and the output number. The task is to find the rule for the function machine.

The teacher demonstrates by first writing the input number on the white board. She then explains to students to now look at the output number. Is it larger or smaller than the input number? If it is smaller, then addition will be the rule and if the output number is smaller, then the solution will be a subtraction rule.  She writes the equation on the board and inserts each answer choice until the current one is found. She completes more examples to ensure understanding.

Students enjoy working with function machines and their number sense and problem-solving skills improve with practice. Complete this algebra activity in your classroom today!

This was a really fun way to get my kids to practice their math. I usually struggle to get them into it and Kids Academy makes it easy.

So engaging
We love how we can focus on math with this app. It is engaging and we love how we are able to adjust and tailor the levels according to our son’s knowledge and skill levels!

Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.
