Aleph Isn't Tough - An Introduction to Hebrew for Adults Book 1 By Linda Motzkin
This is the first step in a program of Hebrew learning for adults with no knowledge of the Hebrew alphabet. It is designed for English-speaking adults who primarily encounter the Hebrew language through Jewish religious life--the prayers and Torah readings in the synagogue, the blessings and rituals of Jewish home observances, and words or phrases arising out of a Jewish cultural context. Adult students who utilize this text will be able to participate more fully in the Hebrew-language aspects of contemporary Jewish life.
If you are learning Hebrew letters for the first time, you may also wish to learn and practice with The New Reading Hebrew, a self-paced book that will help you get on your way to decoding. We also recommend Shalom Hebrew!, a primer designed especially for teens and adults.
