In my years of teaching both preschoolers and P1 children, I have found that one of the most difficult topic to teach is teach children how to analyse questions such as “ 4 is _________ less than 7” or “8 is _________ more than 3”.
I know many parents who are extremely frustrated with trying to help their young ones grasp the concepts behind such questions. I have even seen circumstances whereby parents resorted to finding the various permutations which the questions could be asked and get their children to memorise whether it should be addition or subtraction based on how the questions are phrased.
I do agree with many parents that this type of questions do test a little of English comprehension besides Mathematics understanding. However, I do feel that it is important to provide children with a simple visual model as a heuristic to help them tackle such questions.
