The Instruction Clock is a flexible tool to teach students how to tell time and understand the relationship between analog and digital clocks. You can use it to practice setting the clock, calculating time differences, or working with Roman numerals. The tool makes it easy to display one or two clocks, either digital or analog, so you can adapt it to your lesson.
How it works:
Choose whether you want to show one or two clocks. Each clock can be set to digital or analog.
Use the blue + and – buttons to change the time in steps, or drag the clock hands directly on the analog clock.
Click New time to generate a random time for practice.
Compare two clocks to show time differences or let students practice setting a specific time.
Settings:
You can access the settings by clicking the gear icon in the bottom left corner. Here you can adjust the tool to fit your lesson:
Analog clock options
Watch face: Numerals, Roman numerals, or none.
Hands: Show the hour, minute, and optionally the second hand.
Extra options: Colored or transparent hands, areas with past/to, minutes on the border, 24-hour numerals, colored numbers.
Digital clock options
Choose between 12-hour or 24-hour notation.
Option to color hours and minutes.
General options
Round off time: Change in steps of 1 minute, 5 minutes, quarters, half-hours, or hours.
Color preference: Pick red for hours and blue for minutes, or the other way around.
💡Tip: Use two clocks side by side to let students calculate time differences. For example, set one clock to the current time and ask students to set the other to 45 minutes later. This makes abstract concepts like elapsed time concrete and easy to understand.
