Connecticut Common Core Standards
CT.CC.NBT.4. Number and Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit
arithmetic.
NBT.4.5. Multiply a whole number of up to four digits by a one-digit whole number, and
multiply two two-digit numbers, using strategies based on place value and the properties of
operations. Illustrate and explain the calculation by using equations, rectangular arrays,
and/or area models.
CT.CC.OA.4. Operations and Algebraic Thinking
Use the four operations with whole numbers to solve problems.
OA.4.1. Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7
as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal
statements of multiplicative comparisons as multiplication equations.
OA.4.2. Multiply or divide to solve word problems involving multiplicative comparison,
e.g., by using drawings and equations with a symbol for the unknown number to represent the
problem, distinguishing multiplicative comparison from additive comparison.
OA.4.3. Solve multistep word problems posed with whole numbers and having whole-number
answers using the four operations, including problems in which remainders must be
interpreted. Represent these problems using equations with a letter standing for the unknown
quantity. Assess the reasonableness of answers using mental computation and estimation
strategies including rounding.
