When teaching in a school in the UK, I found most of the small tools I needed online wanted my email, or displayed a lot of ads (sometimes both!)
So, I started making my own resources. They're free, work in any browser, and nothing is stored online.
If you have any suggestions for new tools, let me know at hello@dandruce.co.uk.
A fullscreen countdown for exam conditions. Logs extra time and rest breaks. Large, plain and readable from the back of the classroom.
Drop in a class list, run a league table and/or a knockout competition. Works for competitions or end-of-term quizzes.
Pick a name from a class list. Remembers who you've called on so the same three pupils don't answer every question.
Split a class into groups of N. Optional rules for keeping pupils apart or together.
Chunk a lesson into starter, main and plenary with visible countdowns. Project once, ignore for the rest of the hour.
Sketch a room, drop in names, get a printable plan. Editable in a couple of minutes rather than a free period.
Paste in raw marks and boundaries, get grades back. Works for any exam board or in-house assessment.
There are no ads, no accounts and no premium tier. If something here saved you time, a one-off tip on Ko-fi keeps the domain renewed and the next tool moving.
