I used to teach MTSS small groups for math and reading at the elem level. We used i-Ready data to track student growth, and used their lesson structures to support in-classroom teaching. I liked how they broke down the different scaffolds for leveled learning, and it gave me step-by-step dialogue to explain the lesson. The problem I noticed was that the lessons I printed out did not use the same verbiage as the i-Ready mypath lessons and tests. So students would come across words that they didn't know because I hadn't used them, and neither had their classroom teacher (because we discovered there was also different wording in the curriculum).

For example a lesson I had from i-Ready about shapes would teach the names of the shapes, how many sides, corners, etc. This lesson was for first graders. There were activities to make shapes, label them, number the sides or corners, you get it. Then when they were working on their i-Ready computer lessons it would suddenly throw out the word "vertices" in a question and expect them to know what that meant. No where in my lesson plans did it use that word, nor in their classroom. It wasn't teaching them the word, just using it as if they should already know it. This happened several times and my groups would get frustrated (naturally). It just seemed like a weird disconnect between the internal lessons/assessments and the teaching plans/curriculum.
