4.CE.2

The student will estimate, represent, solve, and justify solutions to single-step and multistep problems, including those in context, using multiplication with whole numbers, and single-step problems, including those in context, using division with whole numbers; and recall with automaticity the multiplication facts through 12 × 12 and the corresponding division facts.

4.CE.2.aDetermine and justify whether an estimate or an exact answer is appropriate when solving contextual problems involving multiplication and division of whole numbers. Refine estimates by adjusting the final amount, using terms such as closer to, between, and a little more than.4.CE.2.bRecall with automaticity the multiplication facts through 12 × 12 and the corresponding division facts.4.CE.2.cCreate an equation using addition, subtraction, multiplication, and division to represent the relationship between equivalent mathematical expressions (e.g., 4 × 3 = 2 × 6; 10 + 8 = 36 ÷ 2; 12 × 4 = 60 –12).4.CE.2.dIdentify and use the appropriate symbol to distinguish between expressions that are equal and expressions that are not equal, using addition, subtraction, multiplication, and division (e.g., 4 × 12 = 8 × 6 and 64 ÷ 8 ≠ 8 × 8).4.CE.2.eDetermine all factor pairs for a whole number 1 to 100, using concrete, pictorial, and numerical representations.4.CE.2.fDetermine common factors and the greatest common factor of no more than three numbers.4.CE.2.gApply strategies (e.g., rounding, place value, properties of multiplication and/or addition) and algorithms, including the standard algorithm, to estimate and determine the product of two whole numbers when given:4.CE.2.hEstimate, represent, solve, and justify solutions to single-step and multistep contextual problems that involve multiplication with whole numbers.4.CE.2.iApply strategies (e.g., rounding, compatible numbers, place value) and algorithms, including the standard algorithm, to estimate and determine the quotient of two whole numbers, given a one-digit divisor and a two- or three-digit dividend, with and without remainders.4.CE.2.jEstimate, represent, solve, and justify solutions to single-step contextual problems involving division with whole numbers.4.CE.2.kInterpret the quotient and remainder when solving a contextual problem.
