The problem is as follows: Lan's house has 4 chicken coops, with 8 chickens in each coop. How many chickens does Lan's house have in total?
The grader wrote that the correct answer is 8 x 4 = 32, while the answer 4 x 8 = 32 is incorrect.
Many parents wonder what the difference is between 4 x 8 and 8 x 4 when both result in 32 and the student's choice must be graded correctly.
