In our school this year, year 7 students have 1 hour per fortnight in a computer suite with a different maths teacher from their other lessons (timetabling issues...). So essentially a “one off” computer room lesson. So far we’ve used Diagnostic Questions in these lessons, but I don’t think this is the best use of students’ time. Any ideas about what else we could be doing? Either as a project over a number of weeks. I suppose I’m looking for things which are “ready to go”, and free or very low cost of course!
