Pennsylvania 1st Grade Math: What Students Learn

Pennsylvania 1st grade math covers a wide range of foundational skills that set students up for success in later grades. Aligned to the Pennsylvania Core Standards in Math, the curriculum focuses on building number sense, operations, measurement, and geometry skills that grow throughout elementary school.

Addition and Subtraction Within 20

First graders in Pennsylvania learn to add and subtract within 20, including solving word problems, adding three whole numbers, and understanding the relationship between addition and subtraction. Students practice using properties of operations and develop fluency with facts within 10.

  • Solve word problems using addition and subtraction within 20
  • Add three whole numbers with sums up to 20
  • Apply properties of operations as strategies
  • Understand subtraction as an unknown-addend problem
  • Relate counting to addition and subtraction

Place Value and Two-Digit Numbers

Students learn that the two digits of a two-digit number represent tens and ones. They count to 120, compare two-digit numbers using the symbols >, =, and <, and practice adding within 100 and finding 10 more or 10 less mentally.

  • Count to 120 starting from any number
  • Understand tens and ones in two-digit numbers
  • Compare two-digit numbers with >, =, and <
  • Add a two-digit number and a one-digit number within 100
  • Subtract multiples of 10 from multiples of 10

Measurement and Data

1st graders order objects by length, measure using whole number units, tell time to the hour and half-hour on analog and digital clocks, and organize data into up to three categories.

Geometry

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