The LEGO DUPLO My First Number Train is designed for children aged 1.5 years and older. This updated version of the classic number train includes 10 brightly colored DUPLO number bricks that fit into the carriages of the push-along train. Children can practice loading and unloading the numbered bricks in sequence, helping develop fine motor skills and early counting abilities from 0 to 10. The set also includes two DUPLO figures (a boy and a girl) and a dog figure to encourage imaginative play. The large, easy-to-grip DUPLO bricks allow young learners to explore number recognition and basic math concepts through hands-on play.
