This is a complete unit, except for assessments, that covers simplifying and evaluating multi-step expressions. I taught this unit last year myself. In my experience it is probably a Tier 1.5 intervention. It's pretty much general education, totally appropriate for your team taught class but especially helpful for your Aut and LD students with executive functioning issues. These are the students who are good at basic math, and somewhat successful at applied math but really struggle with organizing their materials and finding prior notes or models. As always I recommend printing out the entire unit for your kids and handing it to them in one big package.
I used this last year in my self contained, special education classes, and I found that they struggled with a lot of the language. Having everything in one place though was extremely helpful. There were so many gaps in their knowledge that I broke the lessons down into discrete chunks. I personally did a lot of in-between whiteboard activities until my student felt confident with fractions, and integers. You may want to break it down further.
Hope this helps you coast through the year like I did last year!
