Fisher Hill has two easy to use workbooks to learn Spanish. https://www.fisher-hill.com/product-category/spanish-category/ Each workbook has twelve lessons.
Each lesson deals with a common theme, i.e., Breakfast, Telling Time, Shopping, etc. Each lesson is divided into eight parts. The first page is a vocabulary list. Beginning Spanish is included as well as the vocabulary of the particular theme. The definite article is placed in front of each Spanish noun on the list, letting the student know whether it is a feminine or masculine noun. The second page is a conversation which uses the vocabulary in a common situation. Next is a story related to the theme which reinforces the vocabulary and the conversation. The fourth page of each lesson is an exercise that requires choosing a word from the vocabulary list and then writing it in a sentence that is missing that word. The next three pages are a variety of activity pages. At the end of each lesson are the answers to the exercises. At the end of each book are two dictionaries: Spanish-English and English-Spanish.
