I have been using Number of the Day (see separate blog here) for some time and found it to be a useful way of regular revisiting a range of basic number skills.
I began wondering whether it would be possible to use a similar resource to practise basic algebra skills. The result is Expression of the Day.
I haven't had the chance to use this very much yet so it may well get adapted in the coming weeks and months. However, the picture below gives an indication of the kind of questions I might pose to students.
As with Number of the Day, the possibilities for differentiation here are almost limitless.
If you'd like to download the PowerPoint slide it's available here.
If you have any suggestions for changes or improvements, please let me know.
