I kept running into the same problem when I was helping my daughter with math and later while building Math Builders.
The answer was often right. It just was not ready fast enough.
That sounds small until you watch what it does to the rest of the work. A kid can understand the lesson, know what multiplication means, and still get dragged down because every basic fact takes too long to rebuild. By the time they reach the actual problem, a lot of their attention is already gone.
That is the version of "they know it" that I do not trust anymore.
I am not a classroom teacher, so I am not pretending this is some complete intervention framework. I came at it as a parent first and then as the person building a fluency tool. But the pattern was obvious enough that it changed how I think about practice.
