Math in APS

Mathematics instruction in APS is aligned to the five Process Standards for Mathematics developed by the National Council of Teachers of Mathematics and promoted by the Virginia Department of Education. Our goal at Hoffman-Boston Elementary School is to help our students develop into life-long learners and creative problem solvers using the following process standards.

Problem Solving

Students will build new mathematical knowledge through problem-solving; solve problems that arise in mathematics and in other contexts; apply and adapt a variety of appropriate strategies to solve problems; monitor and reflect on the process of mathematical problem-solving.


Students will organize and consolidate their mathematical thinking through communication; communicate their mathematical thinking coherently and clearly to peers, teachers, and others; analyze and evaluate the mathematical thinking and strategies of others; use the language of mathematics to express mathematical ideas precisely.

Reasoning and Proof

Students will recognize reasoning and proof as fundamental aspects of mathematics; make and investigate mathematical conjectures; develop and evaluate mathematical arguments and proofs; select and use various types of reasoning and methods of proof.


Students will recognize and use connections among mathematical ideas; understand how mathematical ideas interconnect and build on one another to produce a coherent whole; recognize and apply mathematics in contexts outside of mathematics.


Students will create and use representations to organize, record, and communicate mathematical ideas; select, apply, and translate among mathematical representations to solve problems; use representations to model and interpret physical, social, and mathematical phenomena.

Mrs. Plunket

I graduated from James Madison University with a Master’s in the Art of Teaching, and have spent my entire professional career so far in elementary classrooms. Before coming to Arlington Public Schools, I taught 5th and 4th grades in Washington, D.C. I taught both 4th and 3rd grades, and serves as the Math Resource Teacher at Hoffman-Boston before transitioning to the role of Math Coach in 2018. As the Math Coach, my role is to work with teachers, students, our administration, and our Hoffman-Boston community to improve student achievement in mathematics.  I love working with our talented teachers to support them in creating positive math communities in their classrooms and developing our students into creative, critical thinkers and persistent problem solvers. When I’m not at Hoffman-Boston, I love to spend time with my husband and our young son enjoying all that Arlington has to offer.
