Mathematical word problem solving difficult analysis and teaching strategy research
——Typical application for primary school mathematics problem solving difficult analysis and teaching strategy research
Abstract
Math word problems is a bridge between mathematics and the interconnectedness of life, but also mathematics teaching and learning difficulties and focus. The topics from mathematics textbooks, teaching, learning, etc., difficult primary problem for some typical applications for analysis, pointing out the different types of math word problems and difficulty focusing on teaching strategies and thus were summarized, pointing out the application difficulties and problems of teaching problem-solving focus.
Keywords:difficulties in analysis; problem-solving procedure; problem-solving ideas
