Simon Sez Santa is an amazing online activity that gets better every year. In it, students act sort of like a TPR (Total Physical Response) teacher by typing in commands, and then “Santa” complies.
They seem to add more and more abilities each year, and it’s always been “kid-friendly.” However, this year they seem to have created two versions — one called “kid-friendly” and the other “nice and naughty.” I haven’t tested-out the second version yet, but I’m hopeful it’s not inappropriate. Unfortunately, the kid-friendly version doesn’t have its own url — you have to go to the main site and then choose one version or the other.
But it’s such a great site for English Language Learners that I’d still use it. You just want to exercise strong oversight when doing so.
