Nonetheless, "We often forget that throughout history, children have happily played without toys and manufactured playthings." Children improvised a wide variety of toys and games using whatever came to hand, including fences, barrels, sticks, stones, and sand. Both children and adults played games such as backgammon, dice, chess and cards, which helped to develop manual dexterity, memory, and strategy. In 1560, Pieter Bruegel the Elder painted "Children's Games". He depicts around 200 children in at least 75 play activities. Only a few activities involved toys made specifically for children, and even fewer might be classed as "educational toys": dolls, simple musical instruments and a water gun used to shoot at a bird.
