We are trying to create item banks for the third grade common core standards. Can you clarify the differences in the two standards below,
3.OA. 4 – Determine the unkown whole number in a multiplication or division equation relating three whole numbers. and 3.OA. 6 – Understand division as an unknown-factor problem.
The are two aspects of the same thing, but the first is about performing a procedure, and the second is about understanding. So, an assessment of the second one might expect a student to come up with an appropriate multiplication equation give a division problem, whereas an assessment of the first one might expect a student to solve a multiplication equation without necessarily relating it to division.
