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

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

• Calculations

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

• Number operations and the relationships between them

• KS2.Ma2.3.a – Develop further their understanding of the four number operations and the relationships between them including inverses; use the related vocabulary; choose suitable number operations to solve a given problem, and recognise similar problems to which they apply

• KS2.Ma2.3.b – Find remainders after division, then express a quotient as a fraction or decimal; round up or down after division, depending on the context

• 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

• ACMNA101 – Solve problems involving division by a one digit number, including those that result in a remainder

#### New Zealand – National Standards expand/collapse

• ##### 7.NA – Number and algebra
• 7.NA.1 – Apply additive and multiplicative strategies flexibly to whole numbers, ratios, and equivalent fractions (including percentages)

• ##### 6.NA – Number and algebra
• 6.NA.1 – Apply additive and simple multiplicative strategies flexibly to:

• 6.NA.1.a – Combine or partition whole numbers, including performing mixed operations and using addition and subtraction as inverse operations

• 6.NA.1.b – Find fractions of sets, shapes, and quantities

#### United States – Common Core State Standards expand/collapse

• ##### 4.OA – Operations & Algebraic Thinking
• Mathematics

• 4.OA.1 – Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

• ##### 5.NBT – Number & Operations in Base Ten
• Mathematics

• 5.NBT.5 – Fluently multiply multi-digit whole numbers using the standard algorithm.
