The Barrington High School Department of Mathematics & Computer Science is dedicated to developing skilled, knowledgeable, and persistent learners and risk-takers that utilize skills and technology appropriately to address meaningful problems and situations. Upon completion of the Barrington 220 mathematics curriculum, students should understand that:

  • Mathematics is ever-present in society and when used appropriately, along with logical reasoning and critical thinking, can help enhance the understanding of real world applications, problem solving, and life-skills.
  • The development of mathematical skills and knowledge allows us to discover the connection between different areas of mathematics and appreciate the natural sequence/progression inherent within.
  • The relevant use of appropriate technology can assist in simplifying, understanding, and making meaning of abstract concepts.
  • The teaching and learning of mathematics not only develops the tools to assist in problem solving, but the ability to decide when to work independently and when to work collaboratively, which can be instrumental in cultivating knowledge and skills.

Graphing Calculator Recommendation

We believe that students should utilize technology appropriately to help them see mathematics, data, and the world in new ways. Graphing calculators are powerful at solving problems quickly that would take a long time by hand. Barrington high school recommends that all students purchase a graphing calculator (TI-84 or similar) in order to visualize mathematics in different ways. There is a year-long rental process for students in financial need. Currently, standardized tests and AP tests only allow handheld calculators, but future digital versions of these assessments may use online calculators such as the one at DESMOS.COM that can be downloaded onto any smartphone or tablet. Students should use their Barrington 220 Gmail login for DESMOS. We will provide exposure to these different types of technology so that students can flexibly learn multiple tools to aid in their mathematics learning.
