Grade 2

Operations and Algebraic Thinking

• Solve challenging addition and subtraction word problems with one or two steps (e.g., a “one-step” problem would be: “Lucy has 23 fewer apples than Julie. Julie has 47 apples. How many apples does Lucy have?”).

• Fluently add with a sum of 20 or less (e.g., 11 + 8); fluently subtract from a number 20 or less (e.g., 16 – 9); and know all sums of one-digit numbers from memory by the end of the year.

• Work with equal groups of objects to gain foundations for multiplication.

Number and Operations in Base Ten

• Understand what the digits mean in three-digit numbers (place value).

• Use an understanding of place value to add and subtract three-digit numbers (e.g., 811 – 367); add and subtract two-digit numbers fluently (e.g., 77 – 28).

Measurement and Data

• Solve addition and subtraction word problems involving length (e.g., “The pen is 2 cm longer than the pencil. If the pencil is 7 cm long, how long is the pen?”).

• Tell time.

• Count money.

Geometry

• Build, draw, and analyze 2-D and 3-D shapes to develop foundations for area, volume, and geometry in later grades.

• Divide shapes into equal shares to build the foundations for fractions in later grades.
