Learning Outcomes/Standards S W Rd Rs T Performance Indicators – Definition/Degree of student performanceOperations and Algebraic Thinking1.OA.5 Relate counting to addition andsubtraction (e.g., by counting on 2 to add 2).X• effectively communicate justifications for sums and differencesby relating the symbolic problems (equations) to appropriatemodels.1.OA.6 Add and subtract within 20,Xdemonstrating fluency for addition andsubtraction within 10. Use strategies such ascounting on; making ten (e.g.,8+6=8+2+4=10+4=14); decomposing anumber leading to a ten (e.g, 13-4=13-3-1=10-1=9; using the relationship betweenaddition and subtraction (e.g, knowing that8+4=12, one knows 12-8=4); and creatingequivalent but easier or known sums (e.g.,adding 6+7 by creating the known equivalent6+6+1=12+1=13).• use addition and subtraction thinking strategies efficiently basedon the values in the problem1.OA.7 Understand the meaning of the equal Xsign, and determine if equations involvingaddition and subtraction are true or false.For example, which of the followingequations are true and which are false? 6=6,7=8-1, 5+2=2+5, 4+1=5+2• partition equal groups of numbers in different ways• Efficiently apply strategies for determining the value of simpleaddition and subtraction mathematical phrases• use strategies for comparing quantities less than 20, (includingusing rational thinking to show equality or inequality ofmathematical phrases)1.OA.8 Determine the unknown wholenumber in an addition or subtractionequation relating three whole numbers. Forexample, determine the unknown numberStudents will complete Math Expressions Unit 2, Quick Quizzes 3 and 4, to relatecounting to addition and subtraction. Students will get at least 8/10.Students will correctly answer 52/64 addition problems and 52/64 subtractionproblems on a written assessment within 5 minutes for each one.When given a written assessment, students will circle number sentences that aretrue (assessment includes both addition and subtraction). Students will get atleast 8/10.• equationStudents will complete Math Expressions Unit 3, Quick Quiz 4, to determine theunknown whole number in addition and subtraction equations with threenumbers. Students will get at least 5/6.
