About this Masterclass
The ability to work systematically, recognise patterns and extend observations to create general rules are all important skills for everyday life as well as being cornerstones of mathematical endeavour.
The aim of the Masterclass is for students to develop their skills in being systematic. They will conduct a mathematical investigation by counting squares in a chessboard, spot patterns and conjecture a rule for a chessboard of any side-length. Thinking systematically will enable them to be sure that they have counted all possible squares without missing any out or double-counting. They will extend their thinking to three dimensions by investigating cubes, starting with a 3x3 cube and developing a rule for cube of any side-length. In a longer Masterclass they will explore other two-dimensional shapes.
Length: 2 hours (see the session leader notes for ideas on how to shorten the Masterclass).
