The pencil box disclosed by the invention is applicable to calculation automatic judging of the primary mathematics.
Description
Technical field:
The present invention relates to a kind of pencil box with primary school mathematics calculating automatic Marking function.
Background technology:
Computing capability is one basic numerical ability of primary school, cultivates pupil and has certain computing capability, is a vital task of primary school math teaching.Calculating the teaching overall process through mathematical education, pupil learns to calculate with the time of nearly half during school, it is seen that calculate the importance in teaching.
The calculation question type of primary school is more single, the most uninteresting, and the accuracy that student calculates is affected bigger by factors such as the interest of student, attitude, customs.In teaching; in order to strengthen student's computing capability; teacher to take a significant amount of time the calculating training repeating student; owing to time in classroom is limited; feedback usually has hysteresis quality, and class's number of student is more simultaneously, and specific aim is the strongest; if teacher and the head of a family have no time to correct in time feedback for child, then child inscribes also with regard to fall flat.Additionally the duplication of labour amount sentencing arithmetic operation of teacher is big, and topic error is sentenced in existence.Proving from teaching practice for many years, the exercise being student is sentenced topic in real time and is corrected mistake in computation in time, and student learning effect is best.
Summary of the invention:
It is an object of the invention to provide a kind of pencil box with primary school mathematics calculating automatic Marking function.
Above-mentioned purpose is realized by following technical scheme:
