Lesson+2+Australian+Maths+Competition+Practice

We started the lesson with the role,by Mrs Rosandich,because Mr Radonich wasn't here. Then we got to work with the 2006 Australian maths competition worksheet. With NO calculators allowed.Fun.

Some of the questions included...

1. The value of 95-83 is .. a) 2 b) 8 c)11 d)12 e)22

2.0.5 expressed as a fraction is A) 1/8 B) 1/5 C) 1/4 D) 1/3 E) 1/2

Pretty easy?...well...it got harder

18. a 1x1x1 cube is cut out of a 10x10x10 cube. Then a 2x2x2 cube is cut from the remainder followed by a 3x3x3 cube and so on. What is the large cube which can be cut out? A) 3x3x3 B) 4x4x4 C)6x6x6 D)7x7x7 E) 5x5x5

the last question on the sheet was....

30. It is a surprising fact that 1x2x3x4x5x6=8x9x10. It is even more surprising that 8x9x10x11x12x13x14 is equal to another such product of consecutive whole numbers. What is the smallest number in this other product?

I think most people used a calculator and Mrs Rosandich kept telling us off. Unsuccessful!( as in, we didn't really listen to her) So..get studying..because we have the actual Australian maths test on Thursday the 6th of august.

Don't forget you can find Australian Maths revision resources on the school website: [] Good Luck... =]
