#### United Kingdom – National Curriculum expand/collapse

• ##### KS2.Ma2 – Number and algebra
• Knowledge, skills and understanding

• Numbers and the number system

• KS2.Ma2.2 – Pupils should be taught to:

• Number patterns and sequences

• KS2.Ma2.2.b – Recognise and describe number patterns, including two- and three-digit multiples of 2, 5 or 10, recognising their patterns and using these to make predictions; make general statements, using words to describe a functional relationship, and test these; recognise prime numbers to 20 and square numbers up to 10 x 10; find factor pairs and all the prime factors of any two-digit integer

• Calculations

• KS2.Ma2.3 – Pupils should be taught to:

• Written methods

• KS2.Ma2.3.j – Use written methods for short multiplication and division by a single-digit integer of two-digit then three-digit then four-digit integers, then of numbers with decimals; then use long multiplication, at first for two-digit by two-digit integer calculations, then for three-digit by two-digit calculations; extend division to informal methods of dividing by a two-digit divisor [for example, 64 ÷ 16]; use approximations and other strategies to check that their answers are reasonable

#### Australia – Australian Curriculum expand/collapse

• ##### Number and Algebra
• Number and place value

• ACMNA100 – Solve problems involving multiplication of large numbers by one- or two-digit numbers using efficient mental, written strategies and appropriate digital technologies
