I love that most of these little interactives don't necessarily have direct connections to the curriculum but I appreciate that (among other things) they say the "Tools are geared towards curiosity" and "Most tools don't explain themselves on purpose.". That makes them great for exploring. Be sure to read the link in the post for a primer but go directly to the interactives by the link below

As an administrator, part of my job is evaluating staff. One of my go to asks is for teachers to work on how they both ask and answer questions of students (I am constantly suggesting that if students ask "is this right?" to always answer with "Tell me why you think it's right" as well as helping students think more like scientists (for both math and science classes). Regardless, here are some other ideas

I always appreciate the work that @DavidButlerUoA does, especially when he puts it all together and shares. In this case, constructions using 2 sides of a ruler. I don't know that this fits into any particular curriculum and that's the beauty of it. It starts with some introductory constructions and quickly ramps up.

Another one about constructions. Though this isn't about how to actually do constructions (you might like my videos on that), it's a nice little set of questions to make specific constructions and then to check them electronically with this site.

Mixed media learning (sounds good). Students complete construction exercises using a pencil, ruler and compasses, then measure a length on their construction. They type it online, which awards the mark if within a given tolerance. www.transum.org/Intro/?ID=403 #mathsresources #mathstoday

I have mixed feelings about timed tests, but they can be useful for motivated students. Regardless I love this interface with the duelling timers and all the options you can use for the questions themselves. And there is not just math but biology, physics, chemistry, computer science and even english.
