Calendar Trick

We are beginning a new calendar year.  This activity is a way to review distributive property and working with fractions, and to introduce polynomials (an expression that consists of a coefficient and variable, and involves operations - add,subtract,multiply,divide). There is more to the definition, but we are working with just one piece at this time.

Students were shown a calendar and a volunteer was asked to secretly pick three numbers and then give me the sum. I then gave them the three numbers that the student had chosen. Then we went through a series of steps as to how to figure it out and how to write an expression.
