The mission of Burr & Burton Academy’s Math Department is to provide all students with a mathematical experience that strives to extend their motivation and abilities for an ever-changing world. This goal is achieved as students engage in rich curricula guided by dynamic teachers in distinct courses that offer appropriate rigor and opportunities.

All Burr and Burton Academy Math students will:
  • have strong number sense
  • have an appropriate mathematical vocabulary
  • have a functional connection between mathematics and the real world
  • have a framework for disciplined, logical thinking that allows them to be creative and agile problem solvers
  • have the ability to effectively communicate their mathematical thinking

The Burr & Burton Math Department believes that technology should be used responsibly in the teaching and learning of mathematics. Technology cannot become a substitute for computational fluency or basic understanding; but the ability to model, extend, and automate is immensely valuable in creating new and exciting opportunities.
Graphing calculators, dynamic geometry software, and other tools will be used in all Burr & Burton math classes. Exactly when and how often will vary by teacher and course.
For all students that anticipate years of studies, culminating with Calculus (which we hope is ALL of you), we recommend the purchase of the.



Information from Gay Dillin, Media Relations Manager at NCTM. NCTM Releases new landmark publication: Focus in High School Mathematics: Reasoning and Sense Making
RESTON, Va., October 6, 2009-The National Council of Teachers of Mathematics (NCTM) today released Focus in High School Mathematics: Reasoning and Sense Making, which suggests practical changes to the high school mathematics curriculum to refocus learning on reasoning and sense making. This shift is not a minor refinement but constitutes a substantial rethinking of the high school math curriculum.
"Reasoning and sense making are at the heart of mathematics from early childhood through adulthood," said NCTM President Henry (Hank) Kepner. "A high school mathematics curriculum based on reasoning and sense making will prepare students for higher learning, career success, and productive citizenship."
NCTM's new publication suggests that the more mathematics instruction builds on what students have previously learned, the more students will be able to learn and retain as they progress from prekindergarten through college. Additionally, focusing on reasoning and sense making has the potential to give coherence to the curriculum and streamline it to improve students' learning of important mathematics. A focus on mathematical reasoning and sense making also helps students to use mathematics more effectively in making wise decisions in the workplace and as citizens.
Reasoning is the process of drawing conclusions based on evidence or stated assumptions-extending the knowledge that one has at a given moment. Sense making is developing understanding of a situation, concept, or context by connecting it with existing knowledge or experience.
The first volume in a series of companion books will also be published this month. Focus in High School Mathematics: Reasoning and Sense Making in Statistics and Probability will be followed by books that offer examples of ways to make reasoning and sense making central in algebra and geometry.
Focus in High School Mathematics: Reasoning and Sense Making was developed with the involvement of high school teachers, mathematics educators, an administrator, mathematicians, and a statistician.
