Second Grade

Overview of Mathematics in Grade 2

In grade two, students will extend their understanding of place value to the hundreds place. They will use this place value understanding to solve word problems, including those involving length and other units of measure. Students will continue to work on their addition and subtraction skills, quickly and accurately adding and subtracting numbers up through 20 and also working with numbers up through 100. They will also build a foundation for understanding fractions by working with shapes and geometry. Activities in these areas will include:

  • Quickly and accurately adding numbers together that total up to 20 or less or subtracting from numbers up through 20
  • Solving one- or two-step word problems by adding or subtracting numbers up through 100
  • Understanding what the different digits mean in a three-digit number
