Tuesday 7th June – Computing

Hello Year 6, 

Whilst we have another day at home due to maintenance at school, you are required to complete home learning for today and bring it to school tomorrow.

For this lesson, you will need:

  • Pen
  • Piece of paper/notebook
  • A sibling/friend/grown-up

LI: To use logical reasoning 

Success Criteria

  • To use directional language correctly.
  • To give step-by-step instructions
  • To follow step-by-step instructions
  • To identify errors in my algorithm
  • To correct errors in my algorithm
  • To use key vocabulary to show how my algorithm worked.

Key vocabulary:

Logical reasoning Logical reasoning means applying rules to problem solving.

Algorithms

An algorithm is a set of instructions. A set of steps must be correctly followed to solve a problem. 

Debug

 Finding these mistakes in an algorithm and correcting them.

On your piece of paper, answer the following questions (try to use the key vocabulary in your answers):

Your turn:

Look at this image:

  • Where have you seen one of these before?
  • What does it do? 

My turn

The image above is of a Beebot, a programmable floor robot. You can program it with simple instructions to move around the floor. In doing so, you will have understood and followed the constraints and rules of a Beebot – that it can only make 90 degree turns and that it moves a set distance each time the arrow key is pressed.

If possible, if you have a sibling or an adult at home, get them to stand at a point in a room and choose an end point. Next, give that person step-by-step instructions to move from that point to your chosen end point. 

For example, if someone chose to start in the corner of the living room and the end point was the door to the living room, their instructions would be something like: “Take 5 steps forward. Turn 90 degrees clockwise. Take 7 small steps forward. Turn 90 degrees anticlockwise and walk 4 steps then stop”. Be as detailed as you can. 

Your turn:

Time to give instructions. Write your instructions down on your piece of paper.

My turn

What you have just done is used logical reasoning to guide that other person to a specific point. The step-by-step instructions were the algorithm. 

If I were to explain how my algorithm worked, I would make sure that I use the key vocabulary to help formulate my answer: I used logical reasoning by using a range of algorithms (a set of instructions) to guide my object to where it needed to be. Whilst doing so, I realised that it was not as easy as I had thought; I had to make changes during the algorithm as it sometimes went wrong.”

Your turn:

On your piece of paper, have a go at writing how you used logical reasoning to make your algorithm work. Don’t’ forget to use the key vocabulary!

Next, if possible, find another person at home and give them a coat/jacket that has been turned inside out. Give that person a set of instructions (similar to the first activity), BUT this time make a deliberate error so they do a step wrong.

For example: “Hold your coat in your right hand, put your left hand down the right sleeve, use your fingers to hold the sleeve opening, pull the sleeve out”.

This mistake is called a bug in coding/logical reasoning. In order to make this algorithm correct again, we must undo the mistake so we can allow the person/object to proceed to the next step. This is called debugging an algorithm. 

_____________________________________________________________________________________________________________

Using logical reasoning to find and fix the bugs:

My turn:

Read the algorithm below. Can you find and fix the bug so that the algorithms match the grids? Here is an example:

Your turn:
Read the algorithms below. Can you find and fix the bug so that the algorithms match the grids? Choose one of the below and compete this on your sheet of paper.

Activity

If possible, find a sibling or grown-up at home (or, you can video call a friend from your class to help with this – please ask an adult first). Set up a small (and safe) obstacle course. The aim of this activity is to use your logical reasoning and knowledge of algorithms and debugging to guide the other person through the obstacle course.

Once you have finished, write an explanation about how you used logical reasoning to make your algorithm work. Use key vocabulary and write about any debugging that you had to do!

If you are finding it a little tricky, rather than using someone at home, you can have a go at using logical reasoning to get from the start to the finish on the grid below. The first step would be, ‘begin at start’.

Make sure you write everything down on your piece of paper/notebook and bring it into school tomorrow.

If you have any questions about the activity, comment below and we will answer them. 

Year 6 Crystal Palace Park trip – Wide games and picnic

Wednesday 18th May 2022. 

Dear families,

Year 6 Crystal Palace Park trip – Wide games and picnic

This is just a reminder to inform you that next Wednesday (25th May), the Year 6 children have their trip to Crystal Palace Park. This was originally going to be at Shirley Hills; however, after carrying out a risk assessment, we decided that it would be safer to have our wide games and picnic at Crystal Palace Park. We will be leaving school around 9.30am and travelling via bus so please could the children be at school at their normal time. We leave the park at 1.30pm and expect to be back at school between 2:45 and 3:00pm depending on traffic. We will inform the school of our progress on the way back. 

Children can wear their own clothes for the trip.  Please ensure that your child has suitable clothing depending on weather, e.g. a light raincoat or sunhat and sun-cream.  They will also need a healthy packed lunch in line with the school’s policy and a bottle of water. Lunches should be in a disposable bag so that the children can throw away any rubbish. There is no need to spending money for this trip. 

If any medication is required (including hay-fever and travel sickness), please give this to your child prior to travel.  If any medication is required for the return journey, please give it to the class teacher in the morning and clearly label with name, class, dosage and time to be taken.

If you have any further questions, feel free to ask a member of the Year 6 team.

Many thanks

The Year 6 team
