Math - FOur fours CHallenge

 Big idea: 
Numbers can be represented in many forms and reflect different relationships.


The objective of this Math challenge is for groups to use their knowledge of order of operations and a combination of four fours to create all the numbers from 1 to 40.     Students could use simple addition ("+"), subtraction ("−"), multiplication ("×"),  division ("÷"), and parentheses as well as more advanced operations that included  factorial ("!"), exponentiation and the square root ("√") operations.
