### Description

In this Function Notation activity, students work collaboratively in groups of 4 to evaluate or solve problems using function notation. There are 6 suits of cards that the groups will work through, together, one suit at a time.

Each group member will pick a card from the same suit and work through their problem. Once all group members have reached their respective solutions, they will add together all of their answers and check their sum with the teacher. If their sum is correct, they will move onto the next suit. If it's not, they must work together to find the error(s), attending to precision while doing so.

The cards are leveled so this is a great differentiated activity. I use the activity in a few ways in my class:

(1) Warmup activity to recap prior skills

(2) Reinforce a Skill during class

(3) Review before a test or quiz

Students love it when we turn it into a competition (which group was the fastest, who worked together the best, who attended to precision the best?). My favorite way to use them is as a warm-up activity since it really sets the tone for the day.

This is designed for an Algebra 1 class, but would be a great refresher for an Algebra 2 class.

There are 6 suits of cards, each suit containing 4 cards that are leveled in difficulty.

Topics Included:

*Evaluating linear functions

*Operations on functions [EX: find f(3)+4, given f(x)=2x+5]

*Finding x, given what f(x) is equal to.

Before using this activity, I always use my function notation notes the day or two before!

### Standards

to see state-specific standards (only available in the US).
Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If π§ is a function and πΉ is an element of its domain, then π§(πΉ) denotes the output of π§ corresponding to the input πΉ. The graph of π§ is the graph of the equation πΊ = π§(πΉ).
Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
