I would love to being using Investigations instead of enVisions.

I miss it very much and am really struggling with how things are taught with enVisions. I feel like we've had to step back to a more traditional way of teaching. My kids do not have the mathematical thinking and number sense they had with Investigations. Yes, I had to supplement for fractions and measurement, but my kids really understood what they were doing and could work flexibly with numbers.
This year I'm having to supplement especially for my high kids and do lots of reteaching (finding better ways to teach concepts) to those who are struggling.
Obviously, no one program is favorite for all of us.
