The manual presents a material that will help to form the skills of oral account on basic topics of the first class: "account within 5", "account within 10", "account within 10 with brackets"," account within 20 "," account in the limits of 20 with brackets", as well as logical examples for training the calculation in a convenient way.
How to understand whether the account skill is brought to automatism? For each sign of action, 3-4 s is assigned. If the child thinks well, then an example is 7–2+3-4-3+7-6+3 = he will solve for 20-25 s, 30 s will be a good result. The correct setting of oral classes in elementary school implies daily and short (5 - 10 min) exercises.
The consistent fulfillment of the tasks of the manual will help students master the skills of the oral account of all forms: a cursory auditory account (the teacher reads aloud a chain of examples, making small stops For the calculation, and the student answers after a few seconds), the visual account (chains of examples are recorded, and the student either reports orally or records), a combined account (the teacher dictates the chains of examples, and the student writes off the answers)
The systematic execution of these tasks develops logical and mathematical thinking, quick wit, strengthens memory and attention. At the discretion of the teacher, the chain of examples can be used both for olympiad and tasks of increased complexity, and for repeating and consolidating the topic. For better assimilation of the material, it is recommended to solve ten examples per day.
Manual can be used in mathematics lessons and for independent work at home
