A City of Towers

This problem is an investigation into combinations of a number of cubes. It is a practical activity which involves working systematically, and visualizing and relating 3D shapes to their representation on paper. Children are asked how many different towers are possible using seven cubes on a base of two of them. The Teachers' Notes page includes suggestions for implementation, discussion questions, ideas for extension and support, and printable handouts (word/pdf).

    • This is a good visual modeling activity for students to learn about possible combinations and representations.

      I'm a cheap breitling watch

    • I'm a cheap breitling watch fan. I love looking at them, feeling them, and admiring them. But, I also realize not everyone who owns or wants to own a luxury watch sees them in the same way.It's no secret that people buy and wear luxury watches for different reasons. While I appreciate their complexity and history, another man might see it as a status symbol. But that's ok! People enjoy breitling replica watches for a variety of different reasons. This is important not because one reason is better than another. Instead, it's important because your reason for buying a watch can often dictate what type of watch you end up purchasing.Take, for example, the biggest decision people make when buying a watch: http://www.repliquedemontres.net.
