, The Evergreen Shoe Factory received an order for 100 pairs of shoes. The factory ships
shoes in cartons that each holds up to 12 pairs. How many cartons will the factory need
to ship this order?
Most of the fourth graders who worked on the problem above gave answers such as 8
R4, 8.333, and 8 1/3 . These responses suggest that the students need practice in
rounding down
expressing remainders
applying number sense
using fractions rather than decimals - ✔✔Option (C) is correct. The question requires an
understanding of equations and number operations. The responses indicate that the
students do not know how to express a reasonable answer. Since the shoes are shipped
in cartons, the number of cartons should be expressed as a whole number and not in
decimals, fractions, or with a remainder.
