Kindergarten Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Grade 6 Grade 7 Grade 8 Algebra IDividing Whole Numbers, Decimals, Fractions, and Rational Numbers(6) Number and operations.The student appliesmathematical processstandards to connectrepeated addition andsubtraction to multiplicationand division situations thatinvolve equal groupings andshares. The student isexpected to:(B) model, create, anddescribe contextual divisionsituations in which a set ofconcrete objects is separatedinto equivalent sets.(4) Number and operations.The student appliesmathematical processstandards to develop and usestrategies and methods forwhole number computationsin order to solve problemswith efficiency and accuracy.The student is expected to:(H) determine the numberof objects in each groupwhen a set of objects ispartitioned into equal sharesor a set of objects is sharedequally.(I) determine if a number iseven or odd using divisibilityrules.(J) determine a quotientusing the relationshipbetween multiplication anddivision.(K) solve one‐step and twostepproblems involvingmultiplication and divisionwithin 100 using strategiesbased on objects; pictorialmodels, including arrays,area models, and equalgroups; properties ofoperations; or recall of facts.(4) Number and operations.The student appliesmathematical processstandards to develop and usestrategies and methods forwhole number computationsand decimal sums anddifferences in order to solveproblems with efficiency andaccuracy. The student isexpected to:(E) represent the quotient ofup to a four‐digit wholenumber divided by a onedigitwhole number usingarrays, area models, orequations.(F) use strategies andalgorithms, including thestandard algorithm, to divideup to a four‐digit dividend bya one‐digit divisor.(H) solve with fluency oneandtwo‐step problemsinvolving multiplication anddivision, includinginterpreting remainders.(3) Number and operations.The student appliesmathematical processstandards to develop and usestrategies and methods forpositive rational numbercomputations in order tosolve problems withefficiency and accuracy. Thestudent is expected to:(C) solve with proficiency forquotients of up to a fourdigitdividend by a two‐digitdivisor using strategies andthe standard algorithm.(F) represent quotients ofdecimals to the hundredths,up to four‐digit dividendsand two‐digit whole numberdivisors, using objects andpictorial models, includingarea models.(G) solve for quotients ofdecimals to the hundredths,up to four‐digit dividendsand two‐digit whole numberdivisors, using strategies andalgorithms, including thestandard algorithm.(3) Number and operations.The student appliesmathematical processstandards to representaddition, subtraction,multiplication, and divisionwhile solving problems andjustifying solutions. Thestudent is expected to:(A) recognize that dividing bya rational number andmultiplying by its reciprocalresult in equivalent values.(E) multiply and dividepositive rational numbersfluently.3) Number and operations.The student appliesmathematical processstandards to add, subtract,multiply, and divide whilesolving problems andjustifying solutions. Thestudent is expected to:(A) add, subtract, multiply,and divide rational numbersfluently.(B) apply and extendprevious understandings ofoperations to solve problemsusing addition, subtraction,multiplication, and divisionof rational numbers©2013 Texas Education Agency.
