1. Games and toys: Teaching children mental arithmetic with games and toys can increase their interest and attraction. For example, use puzzles or building blocks to present numbers, and let children count and simply add and subtract according to the numbers.
2. Digital chart: Create a simple digital chart, which can make numbers and operation symbols with colored cards or cardboard and organize them into mathematical problems. Children can solve problems and do mental arithmetic by moving the position of digital cards.
3. Finger counting: It is a very intuitive method to count the heart with children's fingers. For example, give children a number and let them use their hands to index or perform simple addition and subtraction operations.
4. Counting songs and nursery rhymes: It is an interesting way to teach children's hearts with songs and nursery rhymes about numbers and counting. Through the rhythm and repetition of songs, children can remember numbers and do mental arithmetic more easily.
5, picture presentation: presenting digital problems with pictures or graphics can help children better understand and solve problems. For example, use fruit pictures to represent a certain number of fruits, and let children calculate the total or perform simple addition and subtraction operations.
6, creative exercises: give children some creative exercises, such as drawing, asking for numbers and quantities, or giving children some items, asking them to do mental arithmetic, and exercising their observation and mental arithmetic ability.
7. Practical application: Combining mental arithmetic with real-life situations can help children better understand and apply mental arithmetic. For example, when shopping, ask children to calculate the price and change, or when cooking, ask children to calculate the quantity and share of ingredients.
How to practice mental arithmetic?
Step 1: Simple calculation in action. Start with addition and subtraction and calculate with action. Take one, parents say 1 plus 1, children add one, children quickly report 2, and then calculate 2+ 1=3 until 20. Count to twenty, and then subtract one by one.
Step 2: Pay attention to the formula and action. Analysis: Understanding the concept from action to object to number is a process from quantitative change to qualitative change, so parents must be cautious.
The third step: practice the speed of one to ten anywhere on the paper with simple calculation questions, and let the children add and subtract one quickly after counting. In this way, the practice of adding and subtracting one within ten twenty is quite skilled (one question per second), and the child has developed the habit of fast calculation. After learning other calculations, the child wants to answer as soon as possible.
Step 4: At first, children often miscalculate, but they can feel that they have miscalculated within one second. Analysis: The calculation is actually 1+ 1. Understand this, don't be afraid of others.
Step 5: Practice other calculations step by step. Here is an important tip: just write a piece of paper, 20 questions and one page of training for the calculation questions. Don't be afraid to repeat.
Step 6: Be sure to refuel, and keep practicing to be effective. Children's mental arithmetic ability has been improved, which is very helpful for children's future math study.
