3000 examples in mathematics. 3-4 class. Verbal counting. Extra -table multiplication and division. Uzorova O.V., Nefyodova E.A.

The verbal account has several books included in the general series “3000 examples in mathematics”. Each is devoted to one of the most important software topics that are studied in primary school grades. The number of examples in books is different and increases from class to class, from topic to topic. In total, 3,000 mathematical examples are offered to develop oral skills.

This manual presents the material aimed at the formation of oral account skills on the topic “Extra-table multiplication and division” for grades 3-4.

The oral account develops the quick wits and attention of students, brings up mathematical resourcefulness and strengthens the memory. The correct setting of oral classes in elementary school involves daily and short (from 5 to 10 minutes) exercise. The consistent fulfillment of the tasks of the manual will help students master the skills of the oral account of all forms:

a runaway auditory account. (The teacher verbally calls an example and verbally, after a few seconds, receives an answer.)

The visual score. (Examples are recorded, and answers are either verbally or recorded by students.)

a combined account. (The teacher dictates examples, and the student writes the answers.)

Oral solution of problems.

The speed of the score occurs as a result of long training. But in the first place should be the awareness of certain techniques of oral calculations, and not their mechanical application. The oral account must precede, supplement or conclude the part of the lesson that it is subordinate.

The manual can be used in mathematics lessons, as well as for independent work at home.
