This is a 13-slide Spanish 1 powerpoint that introduces time in Spanish. It includes a description of the terms "Es la" and "Son las", how to add minutes to the hour, helpful phrases such as "media" and "cuarto" and how to tell time after :30 using menos and subtracting from the next hour.
I usually break this lesson up into two days. I review numbers on the first day (0-100) and then complete slides 1-9 on the powerpoint. On the second day I finish the powerpoint and then review time.
