Debugging Challenge

I have been looking at the concepts and approaches behind coding and programming with years 5 & 6. Last week we looked at logical reasoning to not only solve number sequences, but to really explain how the were solved. This enabled us to follow a logical process for each sequence.

This week we are going to apply that skill, and also the skills of decomposition and abstraction to debug some Scratch projects.

Can you find and fix the errors in these projects:

Before you use a computer, have a look at the projects and compare them with the debugged versions. Break down the projects by decomposing them into their individual parts – which parts are not functioning correctly?

Once you think you have found and recorded the bugs, click on the links above, then click on ‘See inside’ and see if you can find and fix the errors. Record what you did on you sheet.

Introducing Scratch to year 3

LO: Can I tinker with Scratch projects?

After last week’s visit from the Sandwich Bot, class 3B are using Scratch for the first time this afternoon.

After an introduction to the Scratch we interface, we will start by looking at four Scratch projects aimed at those just starting on their Scratch journey. To begin with we will ‘tinker’ with these projects. For those new to the word, tinker means to mend or change something by playing and experimenting. This is a great way to start with Scratch, as all projects are completely open source and can be changed by anyone.

Below are links to four projects – start by reading the instructions for each project and see if you can work out what they do.

Then try the following challenges:
– Click on ‘see inside’, what happens if you change some of the blocks?
– Can you make the project do something different?
– Can you add something new to the project?

Bee-bot in Year 1

Year 1 have been using Bee-bots to learn how computers need instructions to function. We began by playing Simon Says, a great game for explaining the importance of accurate instructions. We then experimented with Bee-bots, seeing how we could make them move with the instructions.

Bee-bot is available as a free app on both IOS and and Blue-bot is available for Android tablet devices:

Blue-bot Android

If you have a compatible device, please download these apps and explore them with your child – they’re great fun!

Paper Aeroplane algorithms!

Year 1 have been making and testing algorithms to make paper aeroplanes. We started with a fairly simple dart design. If you would like to have a go at some more complex aeroplanes there are some great templates on I recommend the helicopter and the flying ring – both very different to paper aeroplanes you might be familiar with, but both very effective.
