Nevada 1st Grade Math: What Students Learn

Nevada 1st grade math covers a wide range of foundational skills that set students up for success in later grades. Aligned to the Nevada Academic Content Standards Math, the curriculum focuses on building number sense, arithmetic fluency, and an introduction to measurement and geometry.

Addition and Subtraction Within 20

First graders in Nevada spend significant time adding and subtracting within 20. Students learn to solve word problems, apply properties of operations, and understand subtraction as an unknown-addend problem. They also work toward fluency with addition and subtraction facts within 10.

  • Solve word problems using addition and subtraction within 20
  • Add three whole numbers whose sum is 20 or less
  • Apply commutative and associative properties as strategies
  • Understand the relationship between addition and subtraction

Place Value and Two-Digit Numbers

Students explore the meaning of tens and ones in two-digit numbers. They compare two-digit numbers using the symbols >, =, and <, and practice adding within 100 including adding a two-digit and one-digit number.

  • Understand tens and ones in two-digit numbers
  • Compare two-digit numbers with >, =, and <
  • Add within 100, including two-digit plus one-digit numbers
  • Mentally find 10 more or 10 less than a two-digit number
  • Subtract multiples of 10 from multiples of 10 in the range 10–90

Measurement, Time, and Data

1st grade math introduces students to measuring length, telling time, and organizing data. Students order objects by length, express length in whole units, and tell time to the hour and half-hour using both analog and digital clocks.

  • Order three objects by length and compare indirectly
  • Express length as a whole number of length units
  • Tell and write time in hours and half-hours
  • Organize and interpret data with up to three categories

Geometry

Students distinguish defining from non-defining attributes of shapes, compose 2D and 3D shapes into composite shapes, and partition circles and rectangles into equal shares.

  • Identify defining vs. non-defining attributes of shapes
  • Build and draw shapes with defining attributes
  • Compose two-dimensional and three-dimensional shapes
  • Partition circles and rectangles into two and four equal shares
