United Kingdom – National Curriculum expand/collapse

  • KS1.Y1 – KS1 Year 1
    • Year 1 programme of study
      • KS1.Y1.N.AS – Number - addition and subtraction

        • Pupils should be taught to:

          • KS1.Y1.N.AS.4 – Solve one-step problems that involve addition and subtraction, using concrete objects and pictorial representations, and missing number problems such as 7 = ? - 9

  • KS1.Y2 – KS1 Year 2
    • Year 2 programme of study
      • KS1.Y2.N.AS – Number - addition and subtraction

        • Pupils should be taught to:

          • KS1.Y2.N.AS.5 – Recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems

Australia – Australian Curriculum expand/collapse

  • Year 2
    • Number and Algebra
      • Number and place value

        • ACMNA029 – Explore the connection between addition and subtraction

  • Year 3
    • Number and Algebra
      • Number and place value

        • ACMNA055 – Recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation

New Zealand – National Standards expand/collapse

  • 4 – Year 4
    • 4.NA – Number and algebra
      • 4.NA.1 – Apply basic addition and subtraction facts, simple multiplication facts, and knowledge of place value and symmetry to:

United States – Common Core State Standards expand/collapse

  • K – Kindergarten
    • K.OA – Operations & Algebraic Thinking
      • Mathematics

        • K.OA.2 – Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

  • 1 – Grade 1
    • 1.OA – Operations & Algebraic Thinking
      • Mathematics

        • 1.OA.4 – Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8. Add and subtract within 20.

      • Mathematics

        • 1.OA.8 – 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 = _.

  • 2 – Grade 2
    • 2.OA – Operations & Algebraic Thinking
      • Mathematics

        • 2.OA.2 – Fluently add and subtract within 20 using mental strategies. (See standard 1.OA.6 for a list of mental strategies.) By end of Grade 2, know from memory all sums of two one-digit numbers.
