The teaching of fractional addition and subtraction is an important part of elementary mathematics teaching. Students ’correct grasp of the addition and subtraction of scores can not be ignored for the students’ mathematical learning. Score addition and subtraction, is the basis and conditions for students to learn mathematics, which is the most basic mathematical knowledge. The effectiveness of teaching methods and effectiveness is the relentless pursuit and motivation of every teacher. In primary school mathematics, the addition and subtraction teaching of scores, teachers should make clear their own teaching priorities and difficulties, to find out the feasibility and reliability of teaching steps and links, focusing on training students to score addition and subtraction computing power. Teachers should be based on learning
