LS Mathematics


In kindergarten a concrete, visual and hands-on approach to math foundations is emphasized. Math is taught with a growth mindset that helps develop the students to be creative, flexible problem solvers. While Math in Focus grounds LS math, we also incorporate many engaging, cooperative and project-based materials. Students are encouraged to take risks as they think, develop and explore multiple strategies to solve problems.

Grade 1

First graders will use Math in Focus as a base to understand and develop foundational math concepts with concrete representations, projects and math talks.Students develop and communicate multiple strategies for solving authentic real-life problems and take risks to flexibly think about math concepts that are taught in strands. Some strands/topics include patterns/relationships, number sense and operations, geometry, measurement, data analysis and estimation.

Grade 2

The second grade mathematics program provides students with experiences that build and develop a strong number sense. Through hands on exploration, questioning, games and activities, students study all four operations of whole numbers as well as an introduction to fractions. Students will also work with geometry concepts, money and measurement. Inquiry based problem solving that involve real-life scenarios, cultivates engaging classroom math discourse and analysis.

Grade 3

The third grade mathematics program is designed to provide a strong conceptual base with clear understanding through manipulatives, exploration, questioning, games and activities. Students will study all four operations of whole numbers as well as addition and subtraction of fractions. They are also introduced to decimals. Emphasis, through an integrated curriculum, will be placed on solving real-life problems, including those of money and measurement. Students will work in a cooperative setting that requires predicting outcomes, collecting data, analyzing and discussing strategies and experiences.

Grade 4

The fourth grade curriculum will continue and extend concepts presented in the third grade through the use of manipulatives, explorations, questioning, games and activities. Mathematical operations of whole numbers, fractions, decimals, geometry and graphing will be explored more deeply. Students will be expected to develop a set of "automatic" responses to basic number facts that will facilitate problem solving in everyday life as well as in school. In addition, students will learn to solve multi-step story problems which will help develop their sequential learning skills. Fourth graders will participate in the "World Tour," a yearlong project linking math and social studies.

Grade 5

The fifth grade mathematics curriculum continues to build upon concepts presented and developed in fourth grade. Instructional activities and games will foster independent and cooperative learning and encourage persistence in solving more challenging problems. Concepts introduced include addition and subtraction of integers, fractions, and mixed numbers; ratio and proportion, percentages and statistics; area and volume; and algebraic concepts and skills. Fifth graders will participate in a U.S. History Tour linking the uses of data with their social studies curriculum.
