Acera School, Winchester, MA


Acera is looking for a math educator to design and lead a math block for the 20/21 school year! Bring your highly collaborative spirit, and deep commitment to customizing students’ experiences to fit their needs to our school. We have a core private school program with 130 students ages 5-14, and a robust STEAM based enrichment program that offers year-round classes to the public. We are continuously improving our school as a microcosm of what is possible in education, in which students’ voice, capacities and needs are understood. At Acera, we build relationships with each student as the cornerstone of our practice, and we partner with parents to help each child become the best version of themselves.


Part Time position, for the 20/21 academic year. Start date August 31, 2020.

Math Class Time block is 11a-12p Monday, Tuesday, Thursday and Friday.

In building hours would be 10:15a-1p, and would also include recess coverage.

Optional All Staff Meeting once a week, via Zoom from 3:15-4:30p, day TBD.


 Math Block Teacher Expectations:

  • Customize and/or invent and extend curriculum, leveraging the program that best suits your group (Illustrative Math, Art of Problem Solving, TERC Investigations, Connected Mathematics Program, Singapore Math, other curricula).  Research and plan to find the best strategies for your group, and acquire curricula and tools needed.
  • Differentiate instruction, enabling each student to learn at a rate and in a style that fits him or her best and maximizes their potential. Continuously adapt classroom focus and strategies to accommodate for each student’s needs.
  • A key expectation is that learning goals will be framed, strategies planned, implemented, and revised based upon student interest and need, and that appropriate assessment will be embedded so that students can mark their own progress.
  • Tests can be used in order to have students feel accomplishment and acknowledge mastery and for all to know what is next to learn.
  • Create and adapt individualized learning goals to drive learning approaches and focus for each student throughout the year. Share these with the student’s core teacher for inclusion in the written Individualized Learning Plan.
  • Escalate issues and needs as soon as possible.  If you are struggling to meet students’ needs and need help, it is a sign of strength and confidence to ask for help.
  • Communicate learning goals and strategies to Acera administrators, other math block teachers, core teachers and parents through open exchanges, brief group email updates to your math block group parents once per month, as comments on narrative report cards twice per year, and during parent conferences  (planned and impromptu)
  • Support students who are ready to leap frog ahead of others to do so.  Scaffold a transition to another group or establish an independent sub group as needed.
  • Assign homework as part of middle school level math and above, and only as needed with other groups who are working at the elementary level.
  • Assure that each student makes at least one year of academic mathematical progress, built from where they started at the beginning of the year.  (This is a highly subjective guidepost.)

Additional Responsibilities:

Write Report Cards. It is expected that written drafts for report card comments are submitted to core teachers and an administrator at least 24 hours before report card writing professional day for rapid revision / editing as needed.  This also enables all teachers to include comments into the overall student report card.

Attend Conferences when appropriate.  You can be included in parent conferences alongside with the core classroom teacher for your math students or you may initiate and/or respond to parent requests for individual math conferences.  Confer with each of your students’ core teacher(s) to mutually determine whether conference participation or an individual math conference makes sense.


  • Experience teaching elementary and/or middle school math.
  • A willingness to teach in in-person, online, or hybrid learning environments.
  • Experience in employing a variety of pedagogical approaches for different learning styles.
  • Interest in using technology to enhance teaching and learning.
  • Flexibility and collaborative spirit.
