‘Column Methods’ are the traditional, compact algorithms for solving calculations using pencil and paper. ‘Column Methods’ is a generic title since for all 4 operations we move from column to column addressing each column one at a time.
This book looks at steps of progression for Column Methods and how those steps relate to the steps found in the core numeracy of CLIC.
The starting point for Big Maths is to teach for understanding. Column Methods however are generally low on understanding but they are much more efficient than high-understanding written methods. Column Methods should be taught to complement the high understanding methods of CLIC.
