1998). Supporting this assertion, Alistair McIntosh developed a strategy based program which scaffolds the development of the ‘big ideas’ Wigley, (1996) refers to. Mental Computation Strategies “Mental Computation: a strategies approach” (McIntosh, 2004a), takes teachers much attention was to be given to children’s mental compu-tation of two digit numbers as to single digit computation. Second, the approach was to emphasise not memorisation of individual facts, but the children’s invented or informal strategies for computing the calculations mentally, and their Developing Computation ALISTAIR McINTOSH The study was conducted to explore performance on a variety of mental computation tasks using two presentation formats (visual and oral).

Huw Spanner did some digging in a garden in London on 13 July 2017. This chapter describes some key aspects of early number learning critical to the development of number sense and mental computation, and mathematics generally: counting and estimation, grouping and partitioning, base ten, and arithmetical strategies.

1-11. Alastair McIntosh was born in Doncaster in 1955 but grew up in the village of Leurbost on the Isle of Lewis in the Outer Hebrides. He was educated at the Nicolson Institute in Stornoway. He studied geography (‘submajoring’ in psychology and moral philosophy) at Aberdeen University, graduating in 1977. This study was conducted to obtain information related to mental computation from students in Years 3, 5, 7, and 9 in Western Australia. The numbers of subjects were 163, 163, 163 and 152 in years 3, 5, 7, and 9, respectively.
