• CCSS.MATH.CONTENT.1.OA.A.1
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingRepresent and solve problems involving addition and subtraction

  Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol...

• CCSS.MATH.CONTENT.1.OA.A.2
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingRepresent and solve problems involving addition and subtraction

  Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem....

• CCSS.MATH.CONTENT.1.OA.B.3
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingUnderstand and apply properties of operations and the relationship between addition and subtraction

  Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 ...

• CCSS.MATH.CONTENT.1.OA.B.4
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingUnderstand and apply properties of operations and the relationship between addition and subtraction

  Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8....

• CCSS.MATH.CONTENT.1.OA.C.5
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingAdd and subtract within 20

  Relate counting to addition and subtraction (e.g., by counting on 2 to add 2)....

• CCSS.MATH.CONTENT.1.OA.C.6
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingAdd and subtract within 20

  Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - ...

• CCSS.MATH.CONTENT.1.OA.D.8
  In Grade 1Standards for Mathematical PracticeOperations & Algebraic ThinkingWork with addition and subtraction equations

  Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _....

• CCSS.MATH.CONTENT.1.NBT.A.1
  In Grade 1Standards for Mathematical PracticeNumber & Operations in Base TenExtend the counting sequence

  Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral....

• CCSS.MATH.CONTENT.1.MD.A.2
  In Grade 1Standards for Mathematical PracticeMeasurement & DataMeasure lengths indirectly and by iterating length units

  Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it wi...

• CCSS.MATH.CONTENT.1.MD.B.3
  In Grade 1Standards for Mathematical PracticeMeasurement & DataTell and write time

  Tell and write time in hours and half-hours using analog and digital clocks....

• CCSS.MATH.CONTENT.1.MD.C.4
  In Grade 1Standards for Mathematical PracticeMeasurement & DataRepresent and interpret data

  Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another....

• CCSS.MATH.CONTENT.1.G.A.1
  In Grade 1Standards for Mathematical PracticeGeometryReason with shapes and their attributes

  Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes....
