Here is a kahoot I made to help my 6th grade get a better understanding of "I want to..."
This is pretty high level for 6th grade, in my opinion. But I have been doing lots of intensive games with my students so that they can actually understand the grammar, rather than just using phrases (which I believe should be stopped at 6th grade, anyway LOL). So use at your own discretion for your classes! My kids struggled a little the first time we played, but really got the hang of it the second time, even after I changed the questions around. Feel free to edit my kahoot, as well, to suit your class level.
