What teaching AIDS and learning tools are there every minute?

Teaching AIDS: a teaching aid clock face with an hour hand and a minute hand, a quartz clock with a second hand, and three pictures of getting up and sleeping in class in the book. Learning tool: learning tool clock face with hour hand and minute hand.

By setting teaching objectives, setting teaching process and creating teaching scenarios, students can be brought into corresponding learning scenarios, so as to explore hours, minutes and seconds independently.
