2nd Grade Math (Georgia's K-12 Mathematics Standards)

Mathematical Practices (MP)

• 2.MP Keep going with problems, reason, work with others, explain thinking, use feedback and set learning goals.

Numerical Reasoning (NR)

• 2.NR.1 Use place value to show, read, write and compare numbers to 1,000.
  • 2.NR.1.1 Explain the value of three-digit numbers as hundreds, tens and ones in several ways.
  • 2.NR.1.2 Count by ones from any number within 1,000 and skip count by 5s, 10s, 25s and 100s.
  • 2.NR.1.3 Show, compare and order numbers to 1,000 using place value and >, = and <.
• 2.NR.2 Use part-whole strategies, properties and place value to add and subtract within 1,000.
  • 2.NR.2.1 Add and subtract within 20 fluently using mental part-whole strategies.
  • 2.NR.2.2 Find 10 more, 10 less, 100 more and 100 less than a three-digit number.
  • 2.NR.2.3 Solve two-digit addition and subtraction problems with part-whole strategies.
  • 2.NR.2.4 Add and subtract within 100 fluently using place value, properties and inverse operations.
• 2.NR.3 Work with equal groups to lay the groundwork for multiplication.
  • 2.NR.3.1 Decide if a group of up to 20 objects is odd or even and write even numbers as doubles.
  • 2.NR.3.2 Find the total in arrays up to 5 by 5 using repeated addition and write an equation.

Patterning & Algebraic Reasoning (PAR)

• 2.PAR.4 Recognize, describe, continue and make repeating, growing and shrinking patterns.
  • 2.PAR.4.1 Find, describe and make number patterns built by adding or subtracting the same amount.
  • 2.PAR.4.2 Find, describe and make growing and shrinking patterns using addition and subtraction to 20.

Measurement & Data Reasoning (MDR)

• 2.MDR.5 Estimate and measure lengths and distances in inches, feet and yards.
  • 2.MDR.5.1 Make simple measuring tools from unit pieces and compare them with rulers.
  • 2.MDR.5.2 Estimate and measure lengths to the nearest whole unit with standard tools.
  • 2.MDR.5.3 Find how much longer one object is than another in a standard unit.
  • 2.MDR.5.4 Ask and answer questions about everyday problems using collected data and graphs.
  • 2.MDR.5.5 Show sums and differences of whole numbers on a number line marked in standard units.
• 2.MDR.6 Solve everyday problems about time and money.
  • 2.MDR.6.1 Tell and write time to the nearest five minutes and find elapsed time on a timeline.
  • 2.MDR.6.2 Find the value of a set of coins and solve problems with dollars and cents.

Geometric & Spatial Reasoning (GSR)

• 2.GSR.7 Draw and split shapes with given features and notice shapes in the world.
  • 2.GSR.7.1 Describe, compare and sort flat and solid shapes by given features.
  • 2.GSR.7.2 Find at least one line of symmetry in everyday objects.
  • 2.GSR.7.3 Split circles and rectangles into two, three or four equal shares and name them.
  • 2.GSR.7.4 See that equal shares of the same whole can have different shapes.
