#### 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:

• Fractions, percentages and ratio

• KS2.Ma2.2.e – Understand simple equivalent fractions and simplify fractions by cancelling common factors; compare and order simple fractions by converting them to fractions with a common denominator, explaining their methods and reasoning

• KS2.Ma2.2.f – Recognise the equivalence between the decimal and fraction forms of one half, quarters, tenths and hundredths; understand that 'percentage' means the 'number of parts per 100' and that it can be used for comparisons; find percentages of whole number quantities, using a calculator where appropriate

#### Australia – Australian Curriculum expand/collapse

#### 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)

• ##### 5.NA – Number and algebra
• 5.NA.1 – Apply additive and simple multiplicative strategies and knowledge of symmetry to:

• 5.NA.1.b – find fractions of sets, shapes, and quantities

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

• ##### 4.NF – Number & Operations—Fractions (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, 100.)
• Mathematics

• 4.NF.1 – Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
