Understanding tens and ones

Ten ones can be bundled into one ten. In a two-digit number, the left digit counts tens and the right digit counts leftover ones. The place tells the value of each digit.

Adding within twenty by making ten

To add within twenty, you can count on from the larger number or make a group of ten first. Making ten uses a known pair such as 8 and 2, then adds whatever remains.

Using addition and subtraction fact families

A fact family connects a total with two parts. Addition puts the parts together, while subtraction starts with the total and finds a missing part. The same three numbers can describe these relationships.

What's Taught in 1st Grade Math

1st Grade math deepens number sense and introduces students to addition and subtraction with numbers up to 100. Students explore place value with tens and ones, learn to tell time to the hour and half-hour, measure lengths, and organize data in simple graphs and charts.

Key 1st Grade Math Skills

  • Adding and subtracting within 20 fluently
  • Understanding tens and ones in place value
  • Solving word problems with addition and subtraction
  • Telling time to the hour and half-hour
  • Measuring lengths using non-standard and standard units
  • Identifying and describing 2D and 3D shapes

First graders build directly on Kindergarten counting and number recognition, extending those skills to work with larger numbers and formal operations.

Mastery of 1st Grade addition and place value prepares students for 2nd Grade multi-digit arithmetic, skip counting, and expanded measurement concepts.
