use the 4 operations with positive rational numbers including fractions, decimals and percentages to solve problems using efficient calculation strategies

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

• solving addition and subtraction problems involving fractions and decimals; for example, using rectangular arrays with dimensions equal to the denominators, algebra tiles, digital tools or informal jottings
• choosing an appropriate numerical representation for a problem so that efficient computations can be made, such as \(12.5\)%, \(\frac18\), \(0.125\) or \(\frac{125}{1000}\)
• developing efficient strategies with appropriate use of the commutative and associative properties, place value, patterning, and multiplication facts to solve multiplication and division problems involving fractions and decimals; for example, using the commutative property to calculate \(\frac23\) of \(\frac12\) giving \(\frac12\) of \(\frac23\)=\(\frac13\)
