Family Feud. Maths Online. Monthly Index page::2011 10. Why do this problem? This activity can be a good start for exploring the special properties of shapes. Children benefit from lots of informal play with linking shapes such as Polydron, during which time they conceptualise the different characteristics of 2-d shapes and visualise how they might fold up to make 3-d shapes. This visualising is a very important aspect of being a mathematician.
Possible approach Ask the children to make some squares using Polydron. What is the same/different about them? You could bring in the language of similarity - all squares are the same shape but may be different sizes. The pentomino activity is not a new one, but using Polydron allows children to try lots of examples. Key questions What can you tell me about the square polydrons and the triangular polydrons? What is the same about them? What could 'bigger' mean? Before you fold them up, can you tell what 3-d shape they will make? Possible extension What if you had six squares joined together (hexominoes)? Chances-NCES Kids' Zone. Explore the properties of a straight line graph.
