2020 CCTM Teaching Awardee

About Joe: “Talk less, smile more” is Joe’s philosophy. His passion is to make mathematics meaningful using a variety of techniques including games, group tasks, projects, and real-world problems. Joe knows that math is so much more than number crunching – math is deciding where to put different plants in your garden, math is building a swing for your porch, math is finding the best bus route across town, math is baking and driving and exercising and math is an art.


Dominique Conner

2020 CCTM Teaching Awardee

About Dominique: Dominique’s goal is to continue to find ways to make math instruction more meaningful to students and to find better ways to support them. Dominique finds that many times students come to different conclusions for the problems or want to use different strategies with their teams and that collaboration often means compromising to find the best solution.

2020 CCTM Teaching Awardee

About Elizabeth: Elizabeth consistently runs open-ended problem-solving sessions with her students using high-ceiling, low-floor style problems to ensure that all her students remain actively engaged and challenged throughout.

After, she facilitates the lessons by asking questions to push their thinking and understanding.


Heather Testa

Eyestone Elementary School, Poudre School District, CCTM Region 4
2020 CCTM Teaching Awardee

About Heather: Heather’s students know that they learn MORE by making mistakes and using those mistakes to find a new path to the answer. Heather’s students want to explain their thinking and even question the thinking of others. She tries to create risk takers that want to volunteer instead of feeling like the “victim” when called on. Heather’s students are able to make connections to people, apply the mathematics to practical situations, and explain the mathematics accurately to other students.
