ASL 1 Unit 2 This text offers an introduction to American Sign Language. It is six parts that we believe make up an entire year of language learning. Unit 1 is Introductions and Greetings, Unit 2 is School signs, Unit 3 is Favorite Things, Unit 4 is Family, Unit 5 is Holidays and Seasons, Unit 6 is Cities and States. This book only consists of the signs and basic grammar in ASL. In order to truly learn the language it would be vital to also learn about the Deaf Culture.
