1、1Analysis of elementary school mathematics classroom exercises designed toClassroom practice is the primary teaching an important part of teaching is to test students in classroom learning and an important way to consolidate the knowledge for different class types, the design must focus on classroom
2、 practice. We have been pushing the individualized, that is, different students take different approach to education. In fact, mathematics, too, for different class types, the design of classroom practice is not the same, which requires the design to have for classroom practice of. A new design of t
3、eaching practice 1, the design into practice, such as in teaching, the percentage of problems, I first arranged for a fraction word problems: There are a class of 40 students, of whom 25 were boys, boys accounted for a fraction of the number of class a few? This is a past, students learned the exerc
4、ises, students will soon be able to make it. As long as the fraction of a few to several percent is 2the new lesson content, and so can reduce the sudden introduction, to facilitate students to accept. 2, the design of the consolidation exercise. After the consolidation of the new teaching exercises
5、 designed to pay attention, slope, pay attention to gradual, progressive approach to follow the principles can be arranged in accordance with this process: the prototype problem (and similar examples - to consolidate title (with a slight change example - improve the problem (the integrated use of ne
6、w knowledge. Second, the refresher course design practice 1, focusing on practice. Refresher course training to seize the key knowledge and key capabilities required to enable students to ponder the lesson should be learned by due course of the review focuses collate knowledge, thus strengthening ex
7、ercises designed to be concise, such as two In addition to the review of multi-digit number, may be enough under the highest dividend in addition to, not in addition to the design practice, etc. The purpose is to enable students to master a complete multi-digit number in addition to the calculation
8、rules, 3and be proficient in the calculation. 2, the system exercises. The main purpose of math refresher course is to review the knowledge learned and the knowledge and old knowledge to form the chain, so that knowledge can be formed around a system. 3, the expansion of practice, such as in the rev
9、iew of fractional multiplication and division word problems when students can try to compile the application under known conditions problem: a class of two-thirds of boys and girls the number is, you add a condition and a problem required to compile questions: (1 compiled a fraction multiplication w
10、ord problems; (2 compiled a fraction division word problems, (3 compiled a two-step calculation of the fraction word problems by the students prepared questions, problem-solving scores can be put multiplication, division word problems of the similarities and differences between a good show in front
11、of students so that students master the fraction multiplication and division word problems of nature. 44, a given problem exercises, for example: a dairy farm, a total of 300 cows, including cows and male breast is a 1:9 ratio of the number of Tau, seeking male and female dairy cows have much head? This question can be with a variety of methods to answer (hint: available pro rata method, normalization method, fractional solution, the column equation solution, the ratio method, etc.) Links to free download http:/
