Computing at home – how parents can help

We had a parent’s evening last week at our school. Lots of parents showed a real active interest in computing. A number of people asked me how they could help support learning at home, and which apps or websites to use. Here is a quick summary of the tools I use with the children in school. Where possible I like to use apps which are free, however there are some where there is a small charge.

Key Stage One:

Bee-bot
We have a set of Bee-bots in Foundation Stage, so by the time the children get to year one they are familiar with these great little robots. There is an app which mirrors the physical robots and is a good introduction into how computers need algorithms (instructions) to function.
IOS Bee-bot app (free)

Blue-bot
This is an extension to Bee-bot and lets you see the algorithm as a whole. We will shortly have a set of Blue-bots in school. They do the same as Bee-bots, but can be controlled from an iPad via Bluetooth.
IOS Blue-bot app (free)
Android Blue-bot app (free)

A.L.E.X.
Another free app, which build on the skills learned in Bee-bot. A.L.E.X. is also based on controlling a robot, but with this app you can also build and design your own levels.
A.L.E.X IOS app (free)
A.L.E.X. Android app (free)

Scratch Jr
ScratchJr is a fantastic entry point for children to explore more open ended programming. It introduces characters, background, more movements, repeat loops and basic if/then routines and offers children the opportunity to experiment and play. There are lots of great ideas for projects on the ScratchJr website.

Key Stage Two:

Scratch
The logical next step from ScratchJr, Scratch is a brilliant platform for children to broaden their skills, and to become part of a wider community, sharing their own ideas and borrowing from others. It is a block based platform which all children in Key Stage two will use at Lowerplace. Please see this post for instructions on how to register a Scratch account and why it is a great project to be involved in.

Scratch is web based and needs to be run on a PC or Mac with flash player installed.

Lightbot
Available online, an IOS app or on Android, this is a great too for developing logical thinking and introducing processes into programming. Lightbot also shows that there can be more than one solution to a problem and that some are more efficient than others. There is a free version with a limited number of levels and then paid versions for more levels and challenges.

Lightbot is part of Microsoft’s Hour of Code project, have a look at their website for lots of other great games and activities.
Lightbot free (IOS)
Lightbot full version (IOS) £2.99
Lightbot free (Android)
Lightbot full version (Android) – £2.33

CargoBot
Another app to develop logic and reasoning, but more challenging than Lightbot. The aim is to move pallets around using a crane which you program with loops and repeats. Make sure you start with the easiest levels!
Cargobot IOS (free)
Cargobot Android (free)
Erase All Kittens
This is great fun. There is a free demo version, or for £4 you can buy the full version. Erase All Kittens is a good way of progressing from block based tools such as Scratch to coding using characters, in this case with HTML. It’s a great activity to do with your child, you’ll be surprised what you can learn too.

Swift Playgrounds
This is a new app which has been developed by Apple for iPads. It is based on the Swift programming language which is used to develop many populart iPad apps. It’s not one I have much experience of yet, but I will be introducing it to children in Key Stage two next term.

Physical Computing

In addition to all these great apps and online tools, you can also experience physical computing at home for a reasonably modest outlay.

Codebug
Starting from about £10, codebugs are great little devices which you can program from a computer using a Scratch like interface. It has a set of LED lights which you can control from your computer as well as input and output ports for connecting peripheral devices.

BBC Microbit
Again starting from about £10 the Microbit is similar to the Codebug, but with more resources online.

Raspberry Pi
The Raspberry Pi is a fully functioning computer which fits in the palm of your hand. you can buy one with a Linux operating system for about £45. Once you have connected a monitor, keyboard and mouse you can do pretty much anything you can do on a £1000+ PC or laptop. There are masses of online resources and accessories which you can add to Raspberry Pis such as cameras, sensors and motors – the possibilities are endless.

Crumble Kit
The Crumble is another cheap microcomputer which can perform a variety of functions. The kit comes with the main motherboard, an LED light, a power supply, a servo motor and an ultrasonic sensor. It also has all the wires and connectors you need for basic projects. Once you get familiar with it, you can combine elements, so you could make the light illuminate when the ultrasonic sensor is triggered. This is also programmed through a simple Scratch type interface.

The advent calendar of educational iPad apps day 19 – Scratch Jr

This is the app which gives many children their first experience of coding. In a world where there is a digital skills gap and where an ever increasing number of jobs will be reliant on technical skills, this makes it important. It is very likely that the next Bill Gates or Mark Zuckerberg will have cut their coding teeth on this app.

Scratch Jr is a simplified version of Scratch, a block based programming language. In Scratch Jr, children can code movement, sounds, and conversations for multiple characters using multiple backgrounds. It also includes core concepts of coding and programming such as repeats, loops and if/then events. There is a great bank of resources and lesson plans on the Scratch Jr website, so it’s really easy to get started. Within a couple of lessons even beginners will be comfortable going in their own direction.

It shares a similar look and feel to the full version, so when you are ready to move children on to the full version of Scratch they will be familiar with many of the basic concepts.

Here are some examples of year 2 children coding their own version of The Three Little Pigs in Scratch Jr.

Beyond Bee-bot in KS1

Whenever I introduce a new tool in computing lessons I look for two key features:

1. Does it compliment learning which has already taken place?

2. Is it accessible to be used beyond the four walls of the school?

Having used Bee-bot extensively with years one and two for the last couple of years, I’ve been looking for something to develop programming skills further before moving on to the less structured environment of Scratch Jr. I have in the past gone straight from one to the other, however, with Bee-bot (whether it’s on the app or a physical Bee-bot) you don’t actually get to see the complete algorithm, unless it’s recorded whilst it’s being inputted.

Therefore, I was looking for a tool which you can use to program movement to a specific goal and see the complete algorithm at the end of it. In KS2 I’ve used the brilliant Lightbot from code.org, but this is a little advanced for most of KS1.

The best solution I’ve found so far is A.L.E.X. It’s a robot based game, which seems to appeal to both boys and girls, with some great graphics and nice sound effects. The concept is very similar to Bee-bot, but with a couple of key differences. Firstly, instructions have to be input in one go, rather than one step at a time and secondly the algorithm is displayed in it’s complete form. This means there is a greater reliance on problem solving skills and you can’t use a trial and error approach.

I am also considering using it in years three and four. In addition to completing the levels in the game, there is also an option to design your own levels. This could work well as a paired activity where each child designs a level and challenges their partner to try it out.

Does it compliment learning which has already taken place? Definitely, in that it helps re-enforce what an algorithm is and encourages children to develop their computational thinking. Is it accessible? Again, a big yes – there is a free version with 25 levels on both the App Store and Google Play (an Android version is very important – the cost barrier of iPads means the vast majority of tablets in most children’s homes are Android based) and there is a paid version with additional features available for only £0.79 on both platforms. As a bonus, the free version is ad free.
