Second grade mathematics covers mathematical topics such as fractions, addition and subtraction of two-digit numbers, and collection and presentation of data. Students are also introduced to numbers up to 1,000 and their place values. Other topics include introduction to geometry, mathematical symbols, shapes, and tools for measurement.
Common mathematical symbols taught to second grade kids include the greater than, less than and equal to signs (>,<, and =). Additionally, they are taught about the difference between odd and even numbers.
Common fractions covered at this level include halves, quarters and thirds. Students are taught how to add, subtract, and solve simple equations that involve fractions. Students are required to multiply various numbers by a range of values up to and including 10.
Second grade mathematics also involves the identification of two-dimensional shapes such as square, triangle, rhombus, trapezoid, parallelogram, hexagon, quadrilateral and circle. At this stage, students are required to identify the various shapes and compare and contrast their characteristics. They are also introduced to standard units of measurements when calculating weight, distance, and angles. By the end of second grade, kids should be able to use the appropriate tools such as rulers and thermometers for simple measurements and express these with the correct units.
