For this lesson, we are going to be using spreadsheets.
If you don't have Microsoft office downloaded onto your computer, everyone has access to Excel on their school email account. To access this, log on to your school email and look for the 9 dots that should appear at the top left hand corner of the screen. Once you have clicked on this, you should find the web app by scrolling down. If it doesn't appear, click on the 'G Suite for Education' link, accept everything it asks you to and then find the 9 dots again.
It would be really helpful if you have a practice find Excel with your grown ups before the lesson starts.
