recognise, represent and solve problems involving ratios

How Bloomi helps with this

This is a NAPLAN-year topic. Bloomi teaches it with a short explainer, guided practice, and NAPLAN-style questions — every one traceable to this exact code.

What this looks like in the classroom

• using diagrams, physical or virtual materials to represent ratios, recognising that ratios express the quantitative relationship between 2 or more groups; for example, using counters or coloured beads to show the ratios \(1:4\) and \(1:1:2\)
• using fractions to solve ratio problems involving comparison of quantities and considering part-part and part-whole relations; for example, dividing a set into the ratio \(1:2\) by determining the number of parts as \(3\)
• sharing quantities in a given ratio; for example, sharing an amount of money in a given ratio, such as sharing \(\$20\) in the ratio \(2:3\)
