Clock Timeline - https://app.box.com/s/vtqjv3hgxz66fx2o1gm1
The basic principle with all the slides is that students are challenged to arrange a series of clocks from "earliest" to "latest." In the first slide, accompanying images are given in order to help the student deduce what time of day the clocks are depicting. Later slides simply have pictures of either analog clock faces or digital clocks. These can lead to discussions about what is meant by "earliest" and "latest." Possible questions of discussion include:
How do you know which clocks are showing earlier or later times?
Why is knowing if the time is a.m. or p.m. important?
What happens when it changes to a new day? How many possible right answers might there be then?
Finally, the last slide includes copies of the digits used for the digital clocks so that teachers may easily construct additional excersizes. Simply add the digits by triple tapping them to the clock to get them to stay in place, then shrink the clock to the appropriate size.
