## Investigations involving cube numbers

Children develop more secure understanding when they have the oppotunity to find out the answers for themselves. So, when you come to teach cube numbers to your class, why not try one of these investigations:

1. "What do the following numbers have in common: 8, 27, 64, 125, 216, 343, 512, 729, 1000?

2. "The cube of an odd number is always odd and the cube nu,ber of an even nuber is always even." Is this statement always, sometimes, or never true? Prove it!

3. The first ten cube numbers are: 8, 27, 64, 125, 216, 343, 512, 729, 1000. What are the next ten cube numbers?
