The Birthday Polynomial Project is well known on the internet. This activity incorporates the basic project but also includes two rubrics and a follow up activity. This is an quick and easy way to incorporate this activity into your class!
Students will use a graphing calculator (Desmos.com is recommended in the activity) to create a polynomial based on the digits in his/her birthday. They will change the signs and degrees of a few or all of the terms to create multiple representations. Students are then required to make a written statement about the graph.
Two rubrics are included. The first rubric is for a half time check. This will allow you to assess how the students are making progress. I have included a percentage of these points to be added as bonus on the final assignment.
The final rubric will assess the overall project at the completion of the activity.
After all projects have been complete, a follow up activity is included to work on during class to help the students explore what determines end behaviors and to discuss tangents and zeros that cross the x-axis.
The entire file is editable for you to make it your own.
