Aida solved 9,048 ÷ 58 using the partial quotient strategy. She decided that the quotient is 201. What error did she make?

• She should have subtracted 56 from 100. The answer is 44.

• She added 100 + 50 + 50 + 1 instead of 100 + 50 + 5 + 1. The correct answer is 156.

• She subtracted 3,168 minus 2,900 wrong. It should have been 2,680.

• She should have added 156 to 60. The answer is 216.

Explain why the expression 2+3x4 does not equal 20.

• The student would have to add first because it came first in the problem.

• The student would have to multiply first using PEMDAS.

• The student would have to go straight across the problem to solve. (Like reading)

• The student got it right.
