# Using a Lottery to Illustrate Functions

Grades 9-12 / Math / Functions
CCSS: Math.F.IF.1

Common Core State Standards

 Math Math F Functions IF Interpreting Functions 1 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 f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

Questions to Consider
Why does Mr. Persaud introduce the lottery scenario without using the word 'function'?
How does the term 'one-to-one correspondence' help students understand functions?
Why is it important to revisit functions in this manner even though students were introduced to functions in previous courses?
