Chelli Posted July 23, 2012 Share Posted July 23, 2012 I just got done grading my dd8's test on using bar models (Singapore method). On the problems where she actually had to fill in the bar models, not a word problem, just long bar equals 50, short bar equals 38, missing piece to make short bar equal long bar is a question mark. She missed all of these...every single one. She did the wrong operation every time. On the two-step word problems, though, she got all of them correct. She did not draw bar models, though. Just solved the problems correctly by reading them and figuring out the operations that needed to be used. Of course, I'm going to go over the diagram problems she missed. But my question is this: She obviously understands what to do without using bar models based on getting all of the word problems correct. Is it that important for her to be able to fill in the diagrams correctly? Are the bar model pictures that important (or bar models in general) to Singapore? I'm trying to decide if we need to camp on this topic for a couple of days or if she can move on. Quote Link to comment Share on other sites More sharing options...
