Singapore MOE is very proud of their mathematics modeling , which I do not understand why. The modeling can be solved by algebra sometimes. I also heard many good primary school students in mathematics meet difficulties in secondary school as they could not understand the algebra logic. That is very dangerous. I think they probably did too many modeling questions in primary school until their brain cannot switch or comprehend the simple algebra. I teach both concepts to my boy. Don’t worry, it will not confuse them. He is going to finish all 32x test papers of Primary 4 (left 3x more papers). I hand-picked 14x nice modeling questions from the year 2018 SA1/SA2 test questions that he had completed. He got about 70% right. These 14x questions are very good questions for Primary 4 students. If you can get them all correct, your standard is, surely and definitely in the range of 95%-100%. You probably wonder why I only show the modeling questions of Primary 4 but not other topics.
