Robot Function Machines

Hi everyone!

Function Machines are an exciting, engaging resource to use when teaching algebra to K-2 students.

There are a few different ways of using them...

Write the rule at the top of the robots head e.g +5 and the students can generate the numbers IN by rolling a dice OR you can write the numbers beforehand. OR you can write the answers and the students have to work out the number IN. OR write the IN and OUT numbers and the students have to work out the function! Phew.

I give the younger students counters and cubes to help them work out the answer.

My students love to make "beep, beep" robot sounds when they are working out the answer! They can be used in math centers or as a whole class activity. I use them for addition, subtraction, multiplication and division for all grades. A great differentiated activity which you will use again and again.

Next term I am going to make some 3D robot function machines with my class from recyclable material and tin foil. I'll let you know how that goes!
