The Spanish translation of The Napping House, La casa adormecida, it a great way to reinforce the verb hay (there is/there are). This is a wonderful translation by Alma Flor Ada. The repetition and the rhythm of the lines as something new is added with each page soon have children predicting and repeating the Spanish.
Y en esa casa hay una cama…
Y en esa cama hay una abuela…
Y sobre esa abuela hay un niño…
Y sobre ese niño hay un perro…
The book has beautiful illustrations, and children love looking for the pulga (flea) and the ratón (mouse) on each page. Reading this book is an excellent Spanish language learning experience and a wonderful way to spend time with children.
