Content standard

B4.1.3.2 - Demonstrate an understanding of strategies for comparing, adding and subtracting fractions (same denominator, or one being a multiple of the others)

B4.1.3.2.1 - Compare and order fractions with like denominators by using pictorial representations and finding equivalent fractions using the Lowest Common Denominator (LCD)

Suggested placement

Term 2, Week 2 (Week 14 of the year)

Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

E.g. 1. Use number line or fraction chart to illustrate the concept of comparable fractional units or denominators; i.e. halves, fourths and eighths are comparable; i.e. half can be changed to equivalent fractions in fourths and eighths, and fourths can changed to eighths. Also thirds can changed to sixths.
E.g. 2. Use number line or fraction charts to compare and order unit fractions. Which is larger, 5/8 and 3/4 or 3/6 and 4/8? Arrange from smallest to largest, 3/4, 2/3 and 5/6

E.g. 3. To arrange the fractions, 3/4, 2/3 and 5/6, from largest to smallest, find the Lowest Common Denominator (LCD) and use this to express the equivalent fractions

 The fractions are stacked and are written inline. In E.g. 2 the page prints the pair as "Which is larger, 5/8 and 3/4 or 3/6 and 4/8?" with the fractions set above and below the line of text; a reviewer should confirm the pairing against the page.
