Imagination Stage kicks off its 2017-2018 My First Imagination Stage Season with Cajas, Cajas, Cajas!, a new bilingual version of audience-favorite Boxes, Boxes, Boxes! Best for ages 1 through 5, it runs at Imagination Stage from Nov. 19 to Dec. 3. Cajas, Cajas, Cajas! follows two friends as they use cardboard boxes and their imaginations to build bridges, birds, a train, a plane and even a castle. After the show, the performance is followed by a “free play” session, allowing the audience to build their own creations using props from the show. Performances are Saturdays and Sundays at 10 a.m. and 11:15 a.m. Tickets are $14, with a $5 lap seat for children under 12 months. Tickets may be purchased at imaginationstage.org, at the Imagination Stage box office, or by calling 301-280-1660.
