How to divide the scores of oral calculation cards into three categories? 1, oral arithmetic practice. Practice is based on the textbook, highlighting the key points of central calculation and oral calculation in the textbook. The difficulty is moderate and the questions are diverse. 2, oral calculation tips. This column warmly summarizes the small methods and skills used in oral calculation, reminding children to pay attention to clever calculation while oral calculation. 3. Intelligent gas station. This column is based on oral arithmetic training, presented in the form of application questions and intelligence questions, to consolidate and enhance oral arithmetic ability. The content of "Oral Calculation Question Card (Part IV) (Suitable for People's Parish)" is practical, and the knowledge section is set as needed, which is not cumbersome. It is intended that children's computing ability and skills will be significantly improved and become outstanding students in mathematics through step by step every day.
The choice of oral arithmetic question cards: This set of mouth cards should conform to the guidance of the new curriculum standard, do not give questions randomly, conform to the current period, remind the students with moderate difficulty and the amount of questions, and be suitable for the knowledge learned in class. Let's take a set of oral arithmetic cards in the first volume of mathematics in the fourth grade of People's Education Press as an example. This set of question cards is very well designed. Each page of the title card corresponds to a lesson, including oral calculation, the basic knowledge of this lesson and the training of application problems. The first problem, oral calculation, quick calculation and written calculation, is a basic calculation problem, which aims to train children's agile mathematical thinking ability and cultivate a good sense of numbers. The second type of question is closely related to what you have learned so far, and you can use what you have learned in class to solve problems, thus consolidating your classroom knowledge. The third type of question, mainly applied questions, focuses on cultivating children's logical thinking ability, problem analysis and problem solving ability. Practice at the appointed time every day, don't delay, and form good habits. Establish a good punishment mechanism to encourage children to fall in love with mathematics.
