“…The ability to remember the sequence of numerals up to 10, and then through the teens to 20 and beyond, is a landmark in young children's mathematical development. However, additional components of this development are reasoning and understanding, but these are left out of traditional, rote-based, 'transmission' styles of numeracy teaching that produce relatively low levels of attainment (Askew, Brown, Rhodes, William, & Johnson, 1997;Perry, Vander, Stoep, & Yu, 1993). International studies of teaching effectiveness agree that higher attainment is associated with setting children tasks that require thought rather than practice, and which emphasise the connections between different mathematical ideas (Brown, Askew, Baker, Denvir, & Millett, 1998).…”
