As you guys go through the lessons, it would be great to hear more about aspects that were particularly challenging for your ELL students. For example, @buyskej, if there are particular instructions that you thought needed paring down, we can take a look at those.
Also, I really like the idea of pairing students up for support. When I was in the classroom, a little over half my students were ELL, and it was always a balance between allowing them to work with people in their native language, to ease up on the friction as they tried to learn collaboratively, and having them work in cross-language groups, to support English acquisition. (@tvalentine the majority of my ELL students were Mandarin speakers, though I did have a couple of Russian and a few other languages represented, too (Korean, Spanish, etc.).
