We help students become mathematical thinkers. That means starting with a firm foundation in numbers and operations, algebra, geometry, measurement, data analysis, and probability. We teach with consistent language and strategies that help students develop mental building blocks for higher math and abstract thinking in the upper grades. Grades K-4 use TERC Investigations, a research-based program that emphasizes mathematical thinking and problem-solving. Fifth grade uses Math Expressions, a program that solidifies their conceptual understanding and offers skill and computational practice.
Students explore different types of patterns—repeating, growing, and circular—as part of their thematic studies. They learn to solve problems with addition and subtraction, count 20 or more objects, estimate the number of objects in a collection, and order whole numbers up to 20. Weighing, measuring, keeping track of time and days, and graphing are also part of the math activities in Kindergarten.
An overarching goal in 1st grade is to understand the connection of math and everyday life. Working with calendars and clocks, students continue to develop their understanding of time. Pattern work also continues with students extending, describing, and creating their own. In other units students use 2-D and 3-D shapes to sketch and design, solve problems involving function machines, and read, write, and model whole numbers up to 1,000.
Students focus on learning and communicating different strategies to solve math problems. Increasing automatically in mental and written computation is a goal. While students continue to build their understanding of time, money, and measurement, they also delve into fractions, explore the representation and interpretation of data, and begin to reason with shapes and their attributes. Number order and comparison increases to 10,000.
Geometry units introduce points, intersecting and parallel line segments and rays, linear and area measures, and right angles. Students’ understanding of numbers expands as they compare and order whole numbers up to 1,000,000, use manipulatives to order decimals through hundredths, and compare and order fractions. Solving problems using multiplication is also an area of focus, and students use a variety of strategies, including arrays, mental arithmetic, paper-and-pencil algorithms, and calculators.
The systems of math are emphasized in 4th grade. Students return to pattern work, describing rules for patterns and using them to solve problems. They develop their understanding of place value for multi-digit whole numbers, classify shapes by properties of lines and angles, and deepen their understanding of decimals and fractions. They also solve problems with measurement and conversion from larger to smaller units. Number order and comparison hits a high point of 1,000,000,000.
5th graders use a variety of strategies to solve math problems and can explain how and why they solve problems the way they do. They learn how they can apply the place value structure of the base-ten number system as they add, subtract, multiply, and divide, and they also learn how to describe and apply the associative, commutative, and identity properties. Geometry units include volume and graphing points on a coordinate plane.
