In middle school, we build on the strengths of the lower school program, increasing the amount and range of mathematics explored.  A key component is the development of number sense through mental math.  Calculators are used as tools, and students build mathematical concepts through cooperative hands-on activities.  Students use writing as well as mathematics to express their understanding of concepts.


6th Grade

The curriculum emphasizes conceptual understanding while building upon the mastery of basic skills acquired in the lower school.  The full mathematics spectrum is explored, focusing on how students learn and what they need to be prepared for in the future. 

7th Grade

Problem-solving strategies and critical thinking skills are emphasized in seventh grade.  Subjects include pre-algebra, integers, order of operations, probability and statistics, ratios and proportions, and geometry.  Students study two- and three-dimensional geometry and build models that represent linear and exponential patterns of growth.

8th Grade

Students learn all of the traditional algebraic concepts — linear equations, polynomials, quadratic equations — but encounter them in real-life situations, which prove to be a meaningful and grounded way for students to understand algebra.  On a limited basis, we offer geometry or Stanford University's individualized math program for those students far advanced in mathematics.

  • Seventh Grade Math Gets Real

    Posted April 25, 2013

    Seventh grade students experienced a real-life application of math concepts this week, measuring the height and depth of the steps on a staircase, determining the ratio, and calculating the angle of slope. Math gets real!

  • BHDS Celebrates Pi Day

    Posted March 12, 2013

    Our annual Pi day at BHDS celebrates and explores 3.14, ad infinitum. After measuring the diameter of various circular objects—including a pizza, cookies, plates, and, of course, pies—the students determined both the circumference and area of each...recited "pi-kus" (haikus about pi)...wrote 100-word "pi stories," with the number of syllables of each consecutive word corresponding to the first 100 digits of pi...and of course, consumed the pies...

  • Pi Day Is Sweet at BHDS

    Posted March 14, 2012

    Middle school math classes celebrated Pi Day, making "Pi-Kus" (haikus about pi), "Pi-Lages" (collages of circular images), decorating round cookies to show circumference and diameter, using string cut to the diameter of a circle to measure the circumference, and—naturally—eating pie. Some even competed in a pi recitation contest, to see who could recite accurately the greatest number of pi digits. "I think the students really enjoyed the day," said Alison Frank, math teacher. "Of course, the pie-eating was a huge hit!" The first-ever Pi Day celebration took place at the Exploratorium in San Francisco, the inspiration of now-retired physicist Larry Shaw.

  • Grade 6 Discovers Geometry Is All Around Them

    Posted January 17, 2012

    Our 6th graders discovered that our world contains thousands of geometric shapes, through the Geometric Scavenger Hunt Project, an assignment that asked them to recognize, identify and photograph multiple geometric shapes in everyday life. Students displayed their discoveries via final projects that included digital, poster and 3-D formats. "They'll never see the world in quite the same way again," said teacher Patty Davidovich. "This project really shows students how math is all around us in the tangible, visual world," she added.

  • 6th Grade Does Real Life Math

    Posted April 8, 2011

    Students in 6th grade have been busy applying their many pre-algebra skills by applying them to real life. For example, students have applied their knowledge of concepts like area, radius, diameter and the understanding of pi to create cylinders, and others have applied their knowledge of percents to go on a "shopping spree."
