My Students

My high school students are economically disadvantaged and culturally diverse. I am inspired by many of these young people and their resilience. Some are parenting younger siblings. Others do not have a safe place to sleep each night. Still, others work because they need to contribute to the family income. Most are unable to provide school supplies beyond pen, pencil, and spiral notebooks or paper.

In my classroom, we learn essential math skills, but more importantly, I strive to instill a growth mindset in my students.

These young people often believe they cannot 'do math' or succeed in school. Every teacher, counselor, and administrator in our school strives to help our students to graduate and have a post-graduation plan of action.

My Project

This past summer I attended a professional development provided by the OERB (Oklahoma Energy Resource Board). I received some great tools for my classroom including three rechargeable TI-84 CEs and a charging station for 10 of these calculators. This project will complete the set of 10 calculators and take full advantage of the new charging station!

In AP Statistics students learn how to use the TI-84 to complete complex statistical computations and to analyze data with various graphs.

The batteries never die, the color screen makes reading multiple graphs a breeze, and a complete set will mean every student has access to a working TI-84.
