3000 examples in mathematics. 4th grade. Chain of examples. Multiplication and division of round numbers

The manual presents a material that will help to form the skills of oral account on basic topics of grade 4. Answering the teacher’s questions to each of the following examples, students perform several mathematical tasks - more than 3000 examples.
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 score (the teacher reads aloud a chain of examples, making small stops for calculation, and the student answers after a few seconds), a visual score (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)
Systematic execution These tasks are developing 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 studied 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
