When children get to Year 6, I always find that teaching Internet safety isn't the most exciting of topics since there are only so many ways that I can remind them about the importance of being careful online, having already dome many lessons about it in previous years (without touching on topics such as 'sexting' and 'online grooming' which I strongly believe are much more secondary-appropriate). Having a session recapping on their previous work and discussing any beliefs and misconceptions the children might have is important however - and it also happens to look good if I can say that each year group covers Internet safety.
To begin the lesson, I asked them to complete a short paper activity to help them understand about what should and shouldn't be shared online so any members of the public can read it (via a: blog post, Tweet, uploaded photo etc.):
Following this, I was then determined not to ask them to create yet another (by now not very inspiring) poster with safety rules on so, after much thought, I instead came up with the idea of getting them to design a cardboard phone stand and decorate it with tips for staying safe online.
The stand itself is quite easy to construct - just print out this template onto card (either white or a pale colour; the thicker the better), cut along the solid lines and fold along the dotted lines.
All the children really, really enjoyed the activity - not only because it was something a bit 'different' and involved colouring pencils and highlighting pens, but also because it gave them an actual physical object to take home afterwards. Look at these photos I took of their work to see how well the lesson went.
Finally, to finish off with, I showed the class this Horrible Histories video about privacy settings (and by chance it just so happened that I did the lesson on Bonfire Night too):
Please let me know if you've tried this lesson out with your children - I love reading comments!
