Little tot sports games teach social competence skills
These pseudo sports games for little tots can also teach preschoolers team etiquette and healthy competition (though, according to this resource, any games involving ‘outs’ shouldn’t be introduced at this young age). They can learn how to work together to solve problems, how to be polite with their competitiveness, and how to get along with others.
They can also learn that it’s totally ok if a game doesn’t go as they expected, or if they fell, or tripped, or didn’t see a ball coming. Because it’s just a game.
These things can be learned in an age-appropriate environment, too, where mistakes can be made alongside peers who are developing at the same pace, too.
