Time - 24-Hour Clock - Presentation

The lesson's focus is on mastering the 24-hour clock, with a series of engaging activities aimed at reinforcing the students' ability to convert and understand time in this format. Initially, students are prompted to recap their knowledge of the 24-hour system, specifically how it relates to the conventional 12-hour clock. They are tasked with converting times such as 1 p.m., 4 p.m., and 7 p.m. into 24-hour notation. To make the learning process more interactive, they are encouraged to create a visual diary of their day, marking each event with the corresponding times in both 12-hour and 24-hour formats. This practical application helps to solidify their understanding of the time conversion.

Further activities challenge the students to match times with clock faces that display the same time in 24-hour notation, encouraging them to consider whether the time will be less or more than 12 hours based on whether it's morning, afternoon, or evening. In a series of exercises, students complete times, determine minutes in 24-hour time, and engage in reasoning tasks that require them to prove or disprove statements about time. These exercises not only test their conversion skills but also develop their critical thinking. The lesson culminates with independent work where students must match times to clocks and discuss various aspects of the 24-hour clock, such as understanding when the hour and minute numbers reset.
