Model fractions with denominators of 2, 3, 4, 5 and 8 of whole objects, shapes and collections using concrete materials and diagrams
Examples

Name fractions up to one whole, eg 1/5, 2/5, 3/5, 4/5, 5/5
Examples

Interpret the denominator as the number of equal parts a whole has been divided into
Examples

Interpret the numerator as the number of equal fractional parts, eg 3/8 means 3 equal parts of 8
Examples

Model fractions with denominators of 2, 3, 4, 5 and 8 of whole objects, shapes and collections using concrete materials and diagrams
 Count by quarters, halves and thirds, including with mixed numerals; locate and represent these fractions on a number line (ACMNA078)
