Programming

Year 3

 

Blue-Bots

In Year 3 we have been creating algorithms. We worked in groups to create a sequence of instructions and then our partners had to follow the algorithm using a Blue-Bot. We also had to complete Bee-bot challenges on the computer.

We have also been using Blue-bots and Tactile readers to  create algorithms that will make the Blue-bot move in a square. We had to test our programmes and correct (debug) them if there were any mistakes. Once the Blue-bot moved in a square we tried to change our algorithms so the Blue-bot would move in a rectangle.

Year 6

 

Binary Code

In the Autumn term we learnt about how computers work. We know that wires carry information through the machine in the form of electricity, but do computers actually speak English? Do they store information as sentences that we can understand?

 

We found out that the two options that a computer uses to represent this information are “off” and “on.” When computers represent information using only two options, it's called “Binary.”

Each place that you have a binary option is called a "binary digit" or "bit" for short.

A grouping of eight bits is called a byte.

 

          

 

 

 

Binary Decoder Key

How a computer might represent capital letters

 

Each letter is made of eight bits (one byte), each bit is either black or white (off or on).

We used the decoder key to find out what the initial of our first name was in bytes and then created a binary code bracelet.

We chose two colours (off or on) and took the number of beads we needed in each colour. Then we had to thread the beads onto a pipe cleaner and tie it around our wrist.
