#### 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

#### Australia – Australian Curriculum expand/collapse

• ##### Number and Algebra
• Fractions and decimals

• ACMNA077 – Investigate equivalent fractions used in contexts

• ACMNA078 – Count by quarters halves and thirds, including with mixed numerals. Locate and represent these fractions on a number line

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

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

• ##### 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.

• ##### 3.NF – Number & Operations—Fractions¹ (Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, 8.)
• Mathematics

• 3.NF.3 – Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

• 3.NF.3.a – Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
