Solve problems involving the multiplication and division of two- and three-digit numbers by one digit (2, 3, 4, 5 or 10) with models, arrays and pictures of sets.
-
3.N.15
Determine when an estimate for a problem involving two- and three-digit numbers is appropriate or when an exact answer is needed.
