Every year I make a book where I share with my students a bit about myself, my family, my country of origin, and something fun I did during the summer. I create a short story book and use pictures to illustrate it. I call this book "Todo Sobre Mí." Here is a freebie for you to create your own book to introduce yourself to your students.
