Second Grade Online Math Curriculum

Time4Learning understands how important the choice of a second grade math curriculum is for families. Not only is second grade a time to review the foundational skills learned in first grade math, but it is a launchpad for multiplication and for understanding how numbers are used in everyday life.

The major math strands for second grade curriculum are number sense and operations, algebra, geometry and spatial sense, measurement, and data analysis and probability. Time4Learning teaches a comprehensive second grade math curriculum using fun, activities to build a solid math foundation.

What Math Should a Second Grader Know?

By the time they have finished first grade, students have begun to understand the relationships between numbers and have started to recognize mathematical patterns. Second graders become adept at one and two-digit addition and subtraction and have learned a variety of methods for solving mathematical problems.

Some of the key math concepts a second grader should know include:

  • Read and write numerals to 100 and to count objects to 100 or more
  • Addition and subtraction of two-digit numbers without regrouping, up to 100, using models and algorithms
  • Explore number patterns on a hundred chart and with a calculator
  • Combine shapes to form others shapes and find geometric shapes in real-life situations
  • Learn and compare money values including the quarter (25 cents), half-dollar (50 cents), and dollar (100 cents)

The ideal math curriculum for second grade will continue to build on these skills and expand on to new ones while making learning fun and motivating them to continue to learn.

Second Grade Math Objectives

In second grade, students continue with more sophisticated approaches to addition and subtraction and begin understanding the patterns leading to multiplication. Simple fractions are also introduced this year. Geometric learning extends a student’s understanding of shapes and their parts.

Some of the key goals for second grade math include:

  • Understanding the meaning, uses, and representations for numbers
  • Computing addition and subtraction facts accurately
  • Analyzing and interpreting data
  • Using appropriate techniques, tools, units, and formulas in making measurements
  • Investigating the properties and characteristics of two and three dimensional geometric shapes
