Ohio 1st Grade Math Topics

Ohio's 1st grade math curriculum covers a wide range of foundational skills. Students work through addition and subtraction, place value, measurement, geometry, and data — all aligned to Ohio's Learning Standards Math. StudyPug has a video lesson and practice set for every one of these topics.

Addition and Subtraction

First graders in Ohio learn to add and subtract within 20 using word problems and strategies. They explore properties of operations, the relationship between addition and subtraction, and fluency within 10. StudyPug breaks each strategy into a short, clear video lesson followed by practice problems.

  • Addition and subtraction word problems within 20
  • Adding three whole numbers with a sum up to 20
  • Properties of operations as addition and subtraction strategies
  • Subtraction as an unknown-addend problem
  • Counting on and back to add and subtract
  • Fluency with addition and subtraction within 10
  • Understanding the equal sign and true or false equations
  • Finding the unknown number in addition and subtraction equations

Place Value and Number Sense

Students count to 120 and learn that two-digit numbers are made of tens and ones. They compare numbers using the symbols >, =, and <, and practice adding within 100. These skills form the foundation for 2nd grade math.

  • Counting to 120 starting from any number
  • Tens and ones in two-digit numbers
  • Comparing two-digit numbers with >, =, and <
  • Adding a two-digit number and a one-digit number
  • Adding a two-digit number and a multiple of 10
  • Finding 10 more or 10 less mentally
  • Subtracting multiples of 10 from multiples of 10

Measurement and Data

1st graders order objects by length, express length in whole units, and tell time in hours and half-hours. They also organize and interpret data with up to three categories. StudyPug covers each of these skills with step-by-step video lessons.

  • Ordering three objects by length
  • Measuring length using whole number units
  • Telling and writing time in hours and half-hours
  • Organizing and interpreting data with up to three categories

Geometry

Students distinguish between defining and non-defining attributes of shapes, compose shapes into new ones, and partition circles and rectangles into equal shares. These early geometry concepts prepare students for more advanced work in later grades.

  • Defining versus non-defining shape attributes
  • Composing 2D and 3D shapes into composite shapes
  • Partitioning circles and rectangles into two and four equal shares
