represent natural numbers in expanded notation using place value and powers of 10

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

• investigating exponent notation for powers of \(10\) such as “one hundred thousand” is \(100 000=10×10×10×10×10=10^5\)
• relating the sequences \(10, 100, 1000, 10 000\) … and \(10^1\), \(10^2\), \(10^3\), \(10^4\) ...
• applying and explaining the connections between place value and expanded notations; for example, \(7000=7×10^3\) and \(3750=3×10^3+7×10^2+5×10^1\)
