Forming Expressions from Function Machines WORKSHEET
Suitable for Grades: 8th Grade, Algebra I, IM 1
CCSS: 8.F.A.1, 8.F.A.2
CCSS Description: Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.

Forming Expressions from Function Machines WORKSHEET DESCRIPTION
Function machines can be a good way to help learners form algebraic expressions. This worksheet uses function machines to provide scaffolding to creating algebrtaic expressions and producing a function machine from an expression. This can then need nicely on to using function machines to rearrange simple formulae. In section A, learners need to fill in the boxes to build the expressions from the two-step function machines. Section B does the opposite of Section A. Section C involves a bit more algebraic manipulation with some three-step function machines.
