Mathematics



In Middle School, all the concepts introduced in Lower School Mathematics are reviewed, expanded, and reinforced. To make sure students grasp these concepts, there are two teachers in every classroom, providing individual attention and support. In Fifth Grade, students master the four basic operations of addition, subtraction, multiplication, and division of whole numbers. They also study topics such as fractions, decimals, and percentages and engage in a variety of problem-solving experiences both individually and in small groups.

Sixth graders expand their knowledge even further with geometric formulas, integer concepts, and multi-step problem solving. They also use tables, graphs, written language, and symbolic rules to examine patterns. To bring these concepts to life, students invest imaginary funds in the stock market and use formulas to figure out their gains and losses over time, as well as research a future career and determine a budget to support themselves in NYC.

In Seventh Grade, students continue to learn algebra concepts by exploring ideas through numeric, algebraic, graphical, and verbal perspectives. There is an emphasis on developing students’ abilities to ask probing questions and solve meaningful problems. Topics include: number theory, the real number system, divisors and multiples, equations, mathematical patterns, and systems of linear equations. Students are encouraged to look for patterns within data to formulate predictions, make inferences, and ultimately draw compelling conclusions.  When appropriate, real world applications are explored and technologies, such as Mathematica, Geometer’s Sketchpad, and other web-based tools, are used to promote investigation.
