Naplan 2012 Y5 NC Q34.
(Queensland Studies Authority. www.qsa.qld.edu.au)
Students need to be taught a range of strategies to use to solve word problems. These include:
 reading the problem slowly and carefully several times as this assists with comprehension. In a
teaching situation, reading a problem aloud with the class is a way to model careful reading.
 Discussing the problem using a series of questions models how students should tackle a problem, e.g.
What information is given? Is it all needed? What are the key words/phrases? What are we being asked
to do?

Statements of Learning.
Y5
Students have the opportunity to read and interpret practical problems, identify appropriate operations to use,
express them mathematically and solve them
Y7
They calculate with the four operations, powers of 10 and small whole number powers of other numbers, by
mental, written and technology-assisted methods.

 First mention of these properties yet used in mental computation much earlier and 2 digit by 2 digit
multiplication in Year 6. Supportive of multiplicative thinking where factors used.
