Understanding NJSLS "Math Domains"
Operations and Algebraic Thinking
Understand and evaluate numerical expressions with grouping symbols (parentheses, brackets, and braces); write expressions that represent real-world situations; analyze patterns and describe relationships between numbers.
Number and Operations in Base 10
Understand the meanings, uses, and representations of numbers in our base-10 place-value system; understand and perform operations with multidigit numbers and decimals.
Number and Operations—Fractions
Add and subtract fractions with unlike denominators; multiply fractions and mixed numbers; divide whole numbers by unit fractions and unit fractions by whole numbers; solve real-world problems that involve fractions and computation with fractions.
Measurement and Data
Create and interpret line plots to represent fractional data; convert between measurement units and use conversions to solve real-world problems; understand concepts of volume; find the volume of rectangular prisms.
Geometry
Use and understand a coordinate grid to graph and solve real-world and mathematical problems; understand categories and subcategories of shapes; classify 2-dimensional shapes based on their properties.
