Teachers use it as a math center, a homework set or subtraction review, and one CSI Mini Mystery Detective download covers the week.\u003c\/p\u003e\n\n\u003cp\u003eBorrowing across two columns is the part of the subtraction unit that needs the most practice, and five short cases with a prize and no winner get it practiced with real enthusiasm. Each answer knocks one clue off the list, so every page is self-marking. One CSI Mini Mystery Detective math case a day covers the week.\u003c\/p\u003e\n\u003cp\u003eEvery problem needs borrowing, and some need it across two columns.
