United Kingdom – National Curriculum expand/collapse

  • KS1 – Key Stage 1
    • KS1.Ma2 – Number
      • Knowledge, skills and understanding

        • Using and applying number

          • KS1.Ma2.1 – Pupils should be taught to:

            • Problem solving

              • KS1.Ma2.1.a – Approach problems involving number, and data presented in a variety of forms, in order to identify what they need to do

        • Numbers and the number system

          • KS1.Ma2.2 – Pupils should be taught to:

            • Counting

              • KS1.Ma2.2.a – Count reliably up to 20 objects at first and recognise that if the objects are rearranged the number stays the same; be familiar with the numbers 11 to 20; gradually extend counting to 100 and beyond

            • The number system

              • KS1.Ma2.2.c – Read and write numbers to 20 at first and then to 100 or beyond; understand and use the vocabulary of comparing and ordering these numbers; recognise that the position of a digit gives its value and know what each digit represents, including zero as a place-holder; order a set of one and two-digit numbers and position them on a number line and hundred-square; round any two-digit number to the nearest 10.

Australia – Australian Curriculum expand/collapse

  • Year 1
    • Number and Algebra
      • Number and place value

        • ACMNA013 – Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line

        • ACMNA015 – Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts

New Zealand – National Standards expand/collapse

  • 2 – Year 2
    • 2.NA – Number and algebra
      • 2.NA.1 – Apply counting-on, counting-back, skip-counting, and simple grouping strategies to combine or partition whole numbers

United States – Common Core State Standards expand/collapse

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

        • K.OA.5 – Fluently add and subtract within 5.

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

        • 1.OA.1 – 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 for the unknown number to represent the problem.
