3000 examples in mathematics. Grade 2. Verbal counting. The score is in the range of 100

The oral account has several books included in the total 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 proposed to work out the skills of the oral account.
This manual presents the material aimed at forming the skills of oral account on the topic "account within 100" for grade 2. , 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 orally calls an example and verbally, after a few seconds, receives an answer)
visual score (Examples are recorded, and the answers are either verbally or recorded by students)
Combined score (The teacher dictates examples, and the student writes off the answers) An oral solution to the problems.
The speed of account 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
