Number sense
Number sense is considered as an innate numeracy skill, which not only humans but also some animals, such as fish and birds have. As the name says, it refers to sense of numbers. Number sense enables us to estimate the number of cars on the parking lot without counting them on-by-one, or to tell whether there are more people queueing in one line or in the other one.
APPROXIMATE NUMBER SYSTEM (ANS)
It has been proposed that we use a system called approximate number system, ANS, when estimating magnitudes (e.g. object or dots) approximately, or making comparisons of numbers (1).
When testing what kind of number sense an individual has, researchers often use tasks, in which you need to compare a number of dots or number symbols. Those who have a good number sense often respond quicker and more accurately in these tasks compared to those with weaker number sense.
Look at the pictures.
Can you quickly estimate which of the pictures has more dots?

Development of early mathematical skills
There are several mathematical skills that start to develop already in early childhood, and which have been found to be crucial for good math achievement later on at school. In the iSeeNumbers project, we are interested in finding out
-
how these early mathematical skills develop from first to third grade
-
what kind of individual differences there are in the development, and
-
which mathematical skills, or other factors (e.g., motivation) predict best the later mathematics achievement.
Here we provide a brief description of the mathematical skills that we investigate in the project:
