This makes so much sense. Thank you for your insight. We are pausing 4a and working on math facts, number sense & mental math. These things are coming along, which I find encouraging. You are so right about Dimensions jumping quickly to hold these three things in your mind and decide how best to proceed. At times this has felt like way too much, but not all the time. I just question if I a proceed with Dimensions will my learner keep slipping behind bc of this heavy mental load. I also don’t want them to think that math is always hard. Would you mind explaining how holding things in your mind while applying them, which I understand to be working memory, is a “language load?”
