Second, the memory method
Story memory method: multiplication formula table combined with interesting stories, let children remember the formula through the story plot. Image memory method: using images or graphics to assist memory, connecting numbers with specific images is helpful to deepen memory. Repeated practice: through repeated practice, deepen the understanding and memory of multiplication formula. Parents can practice with their children.
Application of multiplication formula
1, shopping calculation: When shopping, we often need to calculate the price of goods. Using multiplication formula can help us to calculate the total price of goods quickly, especially when we need to buy multiple identical goods, using multiplication formula can save time. Calculating distance: When calculating distance, we can use multiplication formula to calculate the relationship between speed and time.
2. Change: When looking for change, the multiplication formula can help us quickly calculate the amount of change that should be returned. Especially in some places that need accurate calculation and change, such as supermarkets, shops and other places, using multiplication formula can improve efficiency.
3. Statistical data: In statistical data, the multiplication formula can help us to quickly calculate the total number of data. For example, when counting the total number of students in a class, we can use the multiplication formula to calculate the total number of middle school students in a class. Combination problem: When solving some combination problems, the multiplication formula can help us to calculate different combination ways.
