166<br />
of three-year-olds were able to solve<br />
these types of problems when they<br />
involved adding or subtracting a single<br />
item, but their performance decreased<br />
rapidly as the size of the second set<br />
increased.<br />
<strong>Preschool</strong>ers demonstrate the conceptual<br />
understanding and procedural<br />
fluency necessary for them to solve<br />
simple word problems (Fuson 1992b).<br />
Simple word problems are thought<br />
to be easier for preschool children to<br />
solve than number problems that are<br />
not cast in a context (Carpenter and<br />
others 1993). All ages of problemsolvers<br />
are influenced by the context<br />
of the problem and tend to perform<br />
better with more contextual information<br />
(Wason and Johnson-Laird 1972;<br />
Shannon 1999). However, preschool<br />
children tend to be more heavily influenced<br />
by the context of the problem<br />
than do older children and adults,<br />
thus limiting their ability to solve number<br />
problems that are not presented in<br />
context.<br />
Alexander, White, and Daugherty<br />
(1997) propose three conditions for<br />
reasoning in young children: the children<br />
must have a sufficient knowledge<br />
base, the task must be understandable<br />
and motivating, and the context of the<br />
task must be familiar and comfortable<br />
to the problem-solver. These conditions<br />
probably apply to all ages of problem-<br />
solvers (Wason and Johnson-Laird<br />
1972; Shannon 1999).<br />
Researchers indicate that four- and<br />
five-year-olds engage in advanced<br />
mathematical explorations spontaneously<br />
in their play (Ginsburg, Inoue,<br />
and Seo 1999; Seo and Ginsburg<br />
2004). In their everyday activities,<br />
young children spontaneously engage<br />
in a variety of mathematical explorations<br />
and applications such as pattern<br />
analysis, change and transformation,<br />
comparison of magnitude, and<br />
estimations. Any logical thinking that<br />
children exhibit to solve real-life problems<br />
could potentially be considered<br />
beginning mathematical reasoning.<br />
For example, children distributing<br />
the same (or almost same) amount of<br />
snack to classmates or using strategies<br />
to solve immediate situations in<br />
play are situations in which children<br />
begin to demonstrate their ability to<br />
solve mathematical problems. Thus,<br />
it is crucial for teachers to be attuned<br />
to the fact that mathematical reasoning<br />
happens all the time in children’s<br />
lives, and teachers would do well to<br />
use those occasions to nurture children’s<br />
mathematical thinking skills.<br />
The examples illustrate the authentic<br />
problems that occur in preschoolers’<br />
everyday activities and all the different<br />
skills involved in mathematical reasoning<br />
and problem solving.<br />
