My school uses JUMP Math and I fold it into a Kathie-Nunley-style Layered Curriculum Unit. This is the first Number Sense Unit, covering multiplication and division (I usually start there because pre-testing usually shows most of the kids are fine with addition and subtraction so I skip those lessons, remediating where necessary). I use "Level 2, 3, and 4" instead of "C", "B", and "A" because our school uses Ontario's level-based marks instead of letter grades. The download file is in MSWord format, so you can change this back easily.
If you want to know about the activities listed on the sheet, feel free to contact me and I'm happy to share them. I draw on a wide variety of outside resources.
