United Kingdom – National Curriculum expand/collapse

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

        • Calculations

          • KS1.Ma2.3 – Pupils should be taught to:

            • Number operations and the relationships between them

              • KS1.Ma2.3.b – Understand multiplication as repeated addition; understand that halving is the inverse of doubling and find one half and one quarter of shapes and small numbers of objects; begin to understand division as grouping (repeated subtraction); use vocabulary associated with multiplication and division

            • Mental methods

              • KS1.Ma2.3.c – Develop rapid recall of number facts: know addition and subtraction facts to 10 and use these to derive facts with totals to 20, know multiplication facts for the x2 and x10 multiplication tables and derive corresponding division facts, know doubles of numbers to 10 and halves of even numbers to 20

      • Mathematics

        • K.CC.5 – Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.

      • Mathematics

        • K.CC.6 – Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. (Include groups with up to ten objects).

  • 2 – Grade 2

      • Mathematics

        • 2.OA.4 – Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
