Using a format borrowed from "The House That Jack Built," this book for Jewish children explains the traditions of Tu B'Shevat, the Birthday of the Trees. Celebrated on the 15th day of the Hebrew month of Shevat, Tu B'Shevat is traditionally celebrated by the planting of trees. In the book, grandparents share this ritual with their grandchildren. The book serves as an eloquent reminder of the importance of being a good steward of the earth, a lesson aptly passed from generation to generation.
