Last Friday morning, my fourth grader handed me her “Thursday folder” shortly before we needed to head to the bus stop. I was glad to see a perfect spelling test, and a bunch of excellent math assignments and math tests. Time was short, however, so I flipped to the wrong answers. And sprinkled among the math tests, I came across two wrong answers that caused me concern.
Very interesting read...
