Grade 4

A whole new realm of numbers is introduced in fourth grade – those from zero to one. Students learn to manipulate common fractions and mixed numbers in the four basic processes, and are introduced to inequalities. Mental arithmetic now involves multiple steps. Estimation and methods for checking answers are taught.

Grade 5
The fifth grade year begins with a review of the four processes, place value, measurements, rounding, fractions, and word problems. Decimals are then introduced. Students work with the four processes using decimals and practice conversion from fraction to decimal and vice-versa. There is also a focus on order of operations, number systems, mental arithmetic, factorization, and multiple-step word problems. Homework assignments allow for essential practice.

Grade 6
In sixth grade, ratio and proportion, balancing simple equations, and business math form the core of the math curriculum. The class learns the rudiments of basic economics and how to calculate taxes, simple interest, discounts, and other percentages. They also learn how to create and read pie charts and bar and line graphs.

Geometry is also introduced in sixth grade. Students learn the correct use of the compass, straightedge, and protractor. They bisect angles and lines, construct parallel and perpendicular lines, and divide the circle. Students learn to use the number pi and to find the arc of geometric figures. They construct circles, squares, triangles, spirals, and other regular polygons, finally completing a portfolio of geometric drawings in which accuracy and beauty are emphasized.
