Two children are on a concrete patio

Two children are on a concrete patio. A young child in a bright green shirt, patterned pants and blue clogs is kneeling, playing a game on a grey square board on the patio. On the board are a collection of small objects arranged in a pattern. The child is manipulating these objects. Another child, wearing a red shirt and blue shorts, is standing, watching. There is a white sack or bag, a broom, and a purple tub in the background. There are also small white pieces of paper scattered near the tub.
