Scope & Sequence : Scope & Sequence documents describe what is covered in a course (the scope) and also the order in which topics are covered (the sequence). These documents list instructional objectives and skills to be mastered. K12 Scope & Sequence documents for each course include:

Course Overview

Second graders develop an understanding of mathematical operations, and use their understanding to solve problems and apply mathematical concepts to the world around them. Students will continue to deepen their understanding of number sense, place value, computation, estimation, measurement, and geometry. Students will:

  • Work with patterns and sequences
  • Add and subtract two-digit numbers using place value blocks
  • Solve word problems, including problems involving money and time
  • Study measurements of length, weight, and capacity in both metric and standard units
  • Begin to learn about fractions, geometry, and probability
  • Understand basic multiplication and division concepts
