The teacher reviewed vocabulary from the previous class. The student worked on a puzzle with new vocabulary and then completed a story by filling in the correct words. The teacher explained the use of definite articles (el, la, los, las) and indefinite articles (un, una, uno, unas) and how they agree with nouns in Spanish, including the distinction between feminine (-a) and masculine (-o) forms. The student took notes in his notebook and completed an exercise using the correct articles.
