recognise and extend the application of place value to tenths and hundredths and use the conventions of decimal notation to name and represent decimals

How Bloomi helps with this

This is a readiness-year topic that builds towards the next NAPLAN year. Bloomi practises it as curriculum mastery, never test drilling.

What this looks like in the classroom

• using a bar to represent the whole, dividing it into \(10\) equal pieces with each piece representing \(0.1\) or a tenth of the whole length and understanding that \(2\) pieces are \(0.2\) or two-tenths of the whole
• using materials to show the multiplicative relationship between the whole, tenths and hundredths; for example, using a bundle of \(10\) straws to represent the whole, one straw as the tenth and cutting the tenth into \(10\) parts to show the hundredths; using “Decipipes” to represent tenths
• recognising that one is the same as ten-tenths and one-tenth is the same as \(10\) hundredths and using this relationship to rename decimals; for example, renaming \(0.25\) as two-tenths and five-hundredths or twenty-five hundredths
