The manual presents a material that will help to form the skills of an oral account on the topics: “Addition and subtraction in the range of 100 with brackets and without brackets”, “Addition and subtraction type 239+1, 200-1, 350+20, 460-70”, “Multiplication and division of the type 17×3, 51: 3, 51:17, 126: 14”, “Multiplication and division of the type 2×40,” 90: 3, 240: 60 “,” Multiplication and division of round numbers like 170×3, 510: 3, 5100: 170, 1260: 140 “. Answering the teacher’s questions to each of the above examples, students perform several mathematical tasks – only more than 3,000 examples.
The consistent fulfillment of the tasks of the manual will help students to master the skills of the oral account of all forms: a runaway auditory account (the teacher reads the chain of examples aloud, making small stops for calculation, and the student answers in a few seconds), a visual score (chains of examples are recorded and reports orally or records), a combined score (dictated by a dictated teacher Chains of examples, and the student writes the answers).
