ABSTRACT:
The present invention is directed to a learning clock for assisting teachers to teach students how to tell time and learn the correspondence between the time of day according to a traditional clock face or "analog" and the time of day according to strictly numerals or "digital." The clock includes a traditional clock face having an hour hand and a minute hand which are manually rotatable about the clock face and numerals about the clock face for both the hours of the day and the minutes of the hour. The clock also includes a pair of disks for establishing a time of day using strictly numbers. The methods of establishing a time of day operate independent of each other, allowing for a student to match one method to the other.
