What fine motor skill should a child around 4 years old typically be able to demonstrate?

At around 4 years old, children are typically developing their fine motor skills significantly, and one of the abilities they should have is to copy simple geometric shapes, such as a triangle. This skill reflects their increasing control over hand movements and their ability to coordinate visual input with motor output.

Copying a triangle requires not only hand-eye coordination but also an understanding of spatial relationships and the ability to translate those into motor actions on paper. By this age, children are usually able to control a pencil or crayon enough to replicate shapes, indicating their fine motor skills are progressing as expected.

The other choices represent skills that might be expected at different stages of development. For example, writing their name typically develops a little later, as it requires more advanced motor skills and process understanding. Using scissors safely can also be a skill that children are still refining at age four, as it necessitates coordination and control that may not yet be fully mastered. Stacking 10 blocks is an impressive endeavor, but while children can stack blocks around this age, achieving that number of blocks may not universally be mastered by all children at four years old, making it less definitive as a typical fine motor skill.
