New Jersey Mathematics — Grade 3
Comprehensive Course Syllabus
Course Overview
Our New Jersey Grade 3 Mathematics course is designed around the 2023 New Jersey Student Learning Standards for Mathematics (NJSLS-M). Grade 3 represents an important transition into more advanced mathematical thinking, with major emphasis on multiplication, division, fractions, area, measurement, and multi-step problem solving.
