SubtractionAccuracyThis paper reports on a study of two children's mental computation in addition and subtraction, and compares their mental architecture. Both students were identified as being accurate, however, one student used a variety of mental strategies (was flexible) while the other student ...
In written addition, subtraction and multiplication there was a shift from the CAR+to the CAR- strategy (tabulating with, or without, a carried amount) from the third to the later grades. Results show that typical strategies taught at school progressively substitute every other strategy both in ...

To understand the concepts of addition and subtraction, they must first understand the relationship between numbers—for example, the number next to 7 is 8, and 8 is 1 larger than 7. Through the actual counting exercises (along with oral and actual physical counting), combined with the ...
The visual number line is considered a window to understanding the long-standing link between space and numbers in the brain, and even links to wider numerical strategies such as arithmetic (e.g.,Lunardon et al., 2023;Von Aster and Shalev, 2007). Yet, variability in children's number line...
