This time, we have created Scratch, which we hope you will use as a programming learning tool.
Let’s divide seconds, minutes, and hours into units.
Try your hand at “Let’s Make a Digital Clock” and “Let’s Make a Timer 1 (Count Up).”
This time, the “division of units” for hours, minutes, and seconds is already done.
Let’s make a flowchart.
First, let’s think about the process of increasing the timer time by one second at a time using a diagram called a flowchart!
Next, let’s try creating the flow we thought of using a block program.
First, let’s think about a program that changes the “seconds” every second.
How many seconds will it take before the minutes change?
Similarly, how many “minutes” would it take to change the “hour”?
How long can time last?
There is no single algorithm, so it’s interesting to compare your approach (how you calculate the numbers) with your friends!
I think any algorithm that ultimately displays the correct time is “correct”! Please give it a try.
We have also created a worksheet, so please feel free to use it. This time, we have created a simple game that allows you to review .

Remixes are welcome!
This is a Scratch program designed to be remixed and downloaded.
