Do you think computers, phones and tablets are smart? What if we told you that all they understand is two numbers? Stay tuned because this is going to be an eye-opening activity.
You will never think of technology the same way after learning Binary Numbers and Text Encoding!
Did you not get the joke? Don’t worry! We are here to help you brush up on your Computer Language skills!
hello smart parents
If you are not familiar with the activities, please take the time to review the instructions for an optimal learning experience:
hello smart cookies!
We want to introduce you to Dottie and Zac. Dottie is an enthusiastic, ingenious, quick-minded mom who’s curious to understand the world around her. Her son Zac is a very inquisitive, positive and creative kid with a thirst for knowledge.
Join Dottie and Zac while they investigate the secrets around an old computer they found in the attic of their new house. They will need your help to unveil this mystery!
This is going to be no easy feat, but it will definitely be worthwhile fun adventure!
Your first mission is to communicate with that old computer.
Dottie: Interesting… That looks like some sort of really old computer! I wonder if it still works?! Let’s try to turn it on!
Dottie: I don’t think that will work with this computer Zac. There is no keyboard connector. I think these two are the only keys on it…
Zac: So, how are we meant to type in an username?
Zac: What do you mean? Computers have a language?
Dottie: Yes, it is called binary language which only uses binary numbers: zeros and ones.
Dottie: Yes, that sounds right and the computer language is binary code! Do you have a strategy for guessing the username?
Dottie: Hmm, I am afraid we can’t…
Dottie: That is correct, well done! I can help you with that.
Dottie: Let’s break down our complex problem into smaller ones: First, understand how binary numbers work. Second, understand how to translate letters to binary. What do you think the last step could be?
Dottie: Yes, that sounds like a solid plan, doesn’t it?! Well done SMART Cookie! In more technical words, we will use what is called ASCII table to convert characters to decimal numbers, then we can convert the decimal numbers to binary numbers.
Dottie: Well, perhaps you could ask your friends for some help!
You will master the language of computers – also known as binary language, binary numbers or binary code.
Don’t worry if you are still a bit confused. We prepared an activity sheet to help you! It sums up the keys ideas covered in video and some fun practice activities that will get you fluent in Binary!
You should refer to the Activity sheet now!
Make sure to complete Pages 1 and 2 before moving on to the next step as you will need to understand it very well!
Hint! You may find it helpful to play the video again and pause as you go through the it.
Computers are made up of really tiny switches, which are called transistors. Computers use binary numbers to stand for the transistor state. Transistor off = 0. Transistor on = 1.
Well, after all the hard work, we hope you can finally get the joke from the beginning of this post and you can find another one below! Now it’s time to build on your hard work so far and apply your newly gained knowledge to bring binary numbers to life.
How easy is it to count in binary?
It’s as easy as 01 10 11.
Did you not get the joke? Try to think what the numbers mean in binary?!
ASCII to decimal and binary
That was much easier than working out the conversion from decimal to binary, wasn’t it? Well done in learning how binary numbers work and how to use convert letters to number using the ASCII table! You are ready to complete your mission!!!
You should refer to the Activity sheet now!
You can use Page 3 in the Activity Sheet to help you find the binary number for the each of the letters in your name.
Hint! Once you are done, come back here to check your answer using our translator.
Zac: Now, it is your turn my SMART friends to try and see if your name is a valid username for this antique computer?
