In order for students to learn time, they have to understand different increments of time.
This worksheet provides clocks with different activities listed. Students must color each clock, based on the length of time each activity likely takes. For example, taking a photo only take 1 second, so they would color that activity yellow. Activities that take 1 minute to complete will be colored green and activities that take approximately 1 hour to complete will be blue.
I used this with my first graders prior to teaching the unit on time to get an idea of where to begin with each student! Very helpful and effective!
