Math Place Online: Fractions, Decimals & Percents

In this program, teacher leaders, teachers, and parents deepen their math knowledge, develop teaching practices using hands-on and developmental methods, and connect curriculum with the Common Core State Standards.

During the first eight weeks of the program, teacher leaders participate in a course led by Bank Street faculty members Barbara Dubitsky and Robin Hummel to observe, practice, and reflect on the learning experience, math concepts and topics, digital materials, and teaching and learning technologies. The goal is to provide teacher leaders with opportunities to experience constructivist teaching by being the students themselves and to implement their new skills and understanding under the tutelage of Barbara Dubitsky and Robin Hummel.

In the second eight weeks, teachers and parents learn math by doing math. This component is guided by the teacher leaders, as they apply what they learned. Teachers and parents construct their own understanding through problem solving, use of tools, and dialogue in collaborative groups. This course is for teachers and parents to gain a deep understanding of teaching mathematics and the ability to work with learners in productive and meaningful ways.

Common Core Standards

The course will address both the Standards for Mathematical Practice and the Standards for Mathematical Content that involve fractions, decimals, and percents. The Practice Standards are imbedded in the fabric of the course. The Content Standards will be addressed at a very deep level, ensuring that both facilitators and teachers are grounded in the knowledge that will allow them to support conceptual understandings of their students as well as their skills.


“I am learning that math can be fun. There are many learning styles and working with other students helped me see them and learn how to teach with them.”

“One of my favorite parts was that I, for the first time, analyzed what works in solving a problem, looked for patterns, and even analyzed the equations themselves. I liked that in depth learning opportunities. It was enriching.”

“I just love these classes because it is refreshing to look at problems that I would have been nervous about solving. I know  now that it is not about getting the right answer immediately,  and the process of solving the problem is empowering.”

“I liked that we can make a mistake and that we learn from those mistakes--it is not a failure."

“I loved listening to the different ways people solved each problem. It truly helped me to learn to approach math from many different angles.”

“The conversations with Barbara, the math experts and fellow classmates were something that I looked forward to each week. The camaraderie played a big part in understanding and talking out each math problem. Being grouped with others helps to see another's point of view concerning math problems, which can open your eyes to looking at and solving the problem quite differently.”
