1. Watch 3 “Finding least common denominators” videos. In their spiral notebooks, they will write down at least one problem from each video.
2. Watch 2 “Subtracting mixed numbers with borrowing videos. In their spiral notebooks, they will write down at least one problem from each video.
3. Spend at least 30 minutes on the IXL standards listed. Show work.
