A worksheet to use when practicing algebraic reasoning.
This math worksheet challenges students to determine the operation of an input/output machine.
The machine shows an input and the output is always two. Students must determine the rule by deciding if the machine is adding or subtracting, and by how much.
This resource is a great way to practice determining unknown values within an addition or subtraction problem. It would also be a great addition to any second grade celebration at the beginning of the year.
