Heirdsfield, Ann Margaret – Young Children, 2011

Mental computation--that is, calculating in the head--is a relatively new topic in mathematics curricula for primary-age children. It is an important skill because it enables children to learn more deeply how numbers work, make decisions about procedures, and create strategies for calculating, thus promoting number sense--a well-developed…

Mardjetko, Emilia; Macpherson, Julie – Australian Primary Mathematics Classroom, 2007

Mathematical computation consists of both written computation and mental computation. The strategies for mental computation can be used to check the reasonableness of written computations. Mental computation has two distinguishing characteristics: "it produces an exact answer, and the procedure is performed mentally, without using external…

Ineson, Gwen – Perspectives in Education, 2008

The mathematics curriculum in the United Kingdom (UK) has undergone radical changes, placing a particular focus on mental computation. Pupils are not taught written methods of computation until they are able to add and subtract any pair of two digit numbers mentally. Teacher education programmes in the UK have required adaptation to reflect these…

Chavez, Oscar; Reys, Robert; Jones, Dusty – Mathematics Teaching in the Middle School, 2005

Spatial visualization is an important skill that deserves instructional attention. Strong evidence supports the claim that "measures of mathematical ability tend to be strongly correlated with spatial ability" (Anderson 2000). Thus, there is every reason to believe that time spent helping students develop their spatial visualization skills will…

Kartambis, Kathy – Australian Primary Mathematics Classroom, 2007

Research has established that children's development of addition and subtraction skills progresses through a hierarchy of strategies that begin with counting-by-one methods through to flexible mental strategies using a combination of knowledge of basic facts and understanding of place value. An important transition point is the shift from the…

Vale, Colleen – Australian Primary Mathematics Classroom, 1999

Computation activities focusing on speed and accuracy do not provide children with the opportunity to learn or develop their own mental computation strategies. Sets out some goals and ideas for teaching mental computation and introduces a card game for helping children compute mentally. (ASK)

Bobis, Janette – Australian Primary Mathematics Classroom, 2007

Drawing upon research, theory, classroom and personal experiences, this paper focuses on the development of primary-aged children's computational fluency. It emphasises the critical links between number sense and a child's ability to perform mental and written computation. The case of multi-digit multiplication is used to illustrate these…
