Our guide to cultural events in New York City for families with children and teenagers.

CAMP FAIRS at St. Jean Baptiste High School (Jan. 20, noon to 3 p.m.) and Congregation Rodeph Sholom (Jan. 21, noon to 3 p.m.). The winter chill may make sunny hikes and campfire songs seem far away, but this is the time to choose where young family members will spend the summer months. These free fairs, sponsored by New York Family and the American Camp Association of New York and New Jersey, and running on select weekends at various locations through March 11, will each feature 40 to 60 camps, including both day and sleepaway, single-sex and coeducational, and all kinds of themes. Dozens of camp directors will attend, along with Renee Flax, the camp association’s expert.

‘DREAMS OF SAND’ at Flushing Town Hall (Jan. 20, workshop at 1 p.m.; performance at 2:15 p.m.). You could call Borja González the sandman, but he won’t put anyone to sleep. An artist born in Spain, he tells stories with his hands and a fleeting medium: sand. Mr. González will begin this Queens appearance with an interactive workshop in which he’ll teach participants how to work with this material, first on paper and then on a small light table. In his wordless performance, accompanied by music and large projections, he’ll create a narrative about the lives of two people through elaborate drawings of sand.

GUSTAFER YELLOWGOLD at Symphony Space (Jan. 20, 11 a.m.). He may not have been around as long as E.T., but he does hail from outer space and has been thoroughly charming children since 2005: He’s Gustafer Yellowgold, who comes from the sun and from the imagination of Morgan Taylor. A cartoonist and musician, Mr. Taylor creates songs and videos about Gustafer, who looks like an animated drop of butter and now resides in the colder climes of a rather fantastical version of Minnesota. This concert will include songs from Mr. Taylor’s latest CD, “Brighter Side,” which was recently nominated for a Grammy Award for best children’s album.
