\u203bChicoratch is a Scratch program created by Chicodori Guys.
*Image may be an older version<\/p>\n\n\n\n

This time, we have created Scratch, which we hope you will use as a programming learning tool.<\/p>\n\n\n\n

Let’s divide seconds, minutes, and hours into units.<\/h3>\n\n\n\n

Try your hand at \u201cLet’s Make a Digital Clock\u201d and \u201cLet’s Make a Timer 1 (Count Up).\u201d<\/p>\n\n\n\n

This time, the \u201cdivision of units\u201d for hours, minutes, and seconds is already done.<\/p>\n<\/div>\n\n\n\n

Let’s make a flowchart.<\/h3>\n\n\n\n

First, let’s think about the process of increasing the timer time by one second at a time using a diagram called a flowchart!<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
<\/div>\n\n\n\n

Next, let’s try creating the flow we thought of using a block program.<\/h3>\n\n\n\n
\n
\n

First, let’s think about a program that changes the \u201cseconds\u201d every second.<\/p>\n\n\n\n

How many seconds will it take before the minutes change?<\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

Similarly, how many \u201cminutes\u201d would it take to change the \u201chour\u201d?<\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

How long can time last?<\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n
<\/div>\n\n\n\n

There is no single algorithm, so it’s interesting to compare your approach (how you calculate the numbers) with your friends!<\/p>\n\n\n\n

I think any algorithm that ultimately displays the correct time is \u201ccorrect\u201d! Please give it a try.<\/p>\n\n\n\n

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 .<\/p>\n\n\n\n
