Grade 3 – Mathematics++++Current TEKS: Number, Operation, andQuantitatifve ReasoningRevised TEKS (2012) Supporting Information Notes3(2)(B) Number and operations.Thestudent applies mathematical processstandards to represent and compare wholenumbers and understand relationships relatedto place value.The student is expected to describe themathematical relationships found in thebase-10 place value system through thehundred thousands place.3(2)(C) Number and operations.Thestudent applies mathematical processstandards to represent and compare wholenumbers and understand relationships relatedto place value.The student is expected to represent anumber on a number line as beingbetween two consecutive multiples of 10,100, 1,000, or 10,000 and use words todescribe relative size of numbers in orderto round whole numbers.3(3)(G) Number and operations.Thestudent applies mathematical processstandards to represent and explain fractionalunits.The student is expected to explain thattwo fractions are equivalent if and only ifthey are both represented by the samepoint on the number line or represent thesame portion of a same size whole for anarea model.3(4)(I) Number and operations.Thestudent applies mathematical processstandards to develop and use strategies andmethods for whole number computations inorder to solve problems with efficiency andaccuracy.The student is expected to determine if anumber is even or odd using divisibilityrules.The mathematical relationships includeinterpreting the value of each place-valueposition as ten times the position to the right.The revised SE 3(2)(B) builds to the revisedSE 4(2)(A).This builds on number line understandingsfrom grade 2 with Revised SEs 2(2)(E) and2(2)(F).Words may include phrases such as “closerto,” “is about,” or “is nearly.”The emphasis with this revised SE is on theunderstanding that equivalent fractions mustbe describing the same whole. 6/8 does notequal ¾ when the 6/8 is part of a candy barand the ¾ is part of a pizza. While they bothdescribe ¾ of their respective wholes, theamounts described by 6/8 and ¾ are not thesame.To determine if a number is even, one mayapply the divisibility rule for 2: A number isdivisible by 2 if the ones digit is even (0, 2, 4,6, or 8).©2013 Texas Education Agency.
