Tip for Teacher: I found it very easy using PowerPoint (Keynote) to easily draw a square, duplicate it then mowe around the squares looking for answers. Set the fill attribute to no fill or, for the advanced, coloured yellow and aqua with 50% opacity (transparency).

Note to teacher: The starter originally designed for the 27th February was called Texting. It contained a photograph of my mobile phone! How time marches on at a pace and my trusty old phone now looks really dated. Newer phones don’t use predictive text in the same way as they provide a full keyboard so the premise of the Starter is quite dated.

If however you would still like to use that Starter you can find it here: Texting
