Outward Bound Training, also known as Outward Bound Training, originally meant that a small boat left the quiet harbor and plunged into an unknown journey without hesitation to meet the challenges again and again, so as to achieve the purpose of "tempering will, cultivating sentiment, perfecting personality and melting the team".

Outward bound training in primary school mathematics teaching is to enable students to form initial logical thinking ability and spatial concept through outward bound training, and apply them to solve simple practical problems in daily life and production, thus consolidating knowledge and improving skills.

Through the practice in recent years, the outward bound training of primary school mathematics is of great significance in visualizing abstract concepts, living homework and socializing book knowledge.

1. Visualization of abstract concepts

Many knowledge points in primary school mathematics textbooks are abstract. If teachers impose this knowledge on students in teaching, they will lose their enthusiasm for learning. As a teacher, we should let students operate by themselves through outward bound training, and put some abstract concepts in front of students vividly, so that students can really feel them. Practice has proved that students' interest in learning will be stronger, the classroom will be more active, teachers will be easy to teach and students will be happy to learn, thus improving teaching efficiency and getting twice the result with half the effort.
