8-year-olds like to have fun, for sure. They enjoy vigorous activities like riding bikes, playing sports, and anything that works up a sweat. They also like more focused activities, including drawing, puzzles, and playing with toys that build up science, math, and language skills. Some 8-year-olds might take up an instrument and others might want to put on a show. All around, 8-year-olds have got a lot of energy and are ready to put it to good use (source).
