This powerpoint lesson has 44 slides that guide you through teaching students how to tell time in Spanish. I can spend 1 or 2 days on this usually depending on how large the class are. I use laminated blank clock faces with this lesson so students can work along with the lesson to practice the concepts. This hands-on approach has really helped some of my high school students who previously could not read an analog clock at all. I hope it works well for you too!
