1st Grade Math Topics Covered

StudyPug covers all major 1st grade math topics required by North Dakota Mathematics Standards. From adding and subtracting within 20 to understanding place value and shapes, every lesson is designed to match exactly what North Dakota 1st graders learn in school.

Addition and Subtraction

1st graders learn to use addition and subtraction within 20 to solve word problems. Topics include adding three whole numbers, applying properties of operations, and understanding subtraction as an unknown-addend problem. Students also build fluency for addition and subtraction within 10.

  • Solve word problems using addition and subtraction within 20
  • Add three whole numbers with a sum up to 20
  • Understand the equal sign and true or false equations
  • Find the unknown number in addition and subtraction equations

Place Value and Number Sense

Students learn to count to 120 starting from any number, understand tens and ones in two-digit numbers, and compare two-digit numbers using >, =, and < symbols.

  • Count to 120 starting at any number
  • Understand tens and ones in two-digit numbers
  • Compare two-digit numbers with >, =, and <
  • Add within 100 including two-digit and one-digit numbers
  • Mentally find 10 more or 10 less than any two-digit number
  • Subtract multiples of 10 from multiples of 10

Measurement and Data

1st graders order objects by length, express length in whole units, tell time to the hour and half-hour, and interpret data with up to three categories.

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

Geometry

Students explore defining attributes of shapes, compose two-dimensional and three-dimensional shapes, and partition circles and rectangles into equal shares.

  • Identify defining versus non-defining attributes of shapes
  • Compose 2D and 3D shapes to create composite shapes
  • Partition circles and rectangles into two and four equal shares
