1, learn the estimation rules.
It is estimated that a rough calculation can be used to get a rough result. We can quickly get a reasonable answer range by hand calculation or oral calculation. When estimating, we need to consider the relationship between the size of the numbers, and then make a rough calculation. For example, we can judge whether the result to be estimated is reasonable through knowledge background and experience, and then adopt appropriate calculation methods.
2. Improve the evaluation ability
Estimation is a very practical mathematical skill, which can help us get the correct answer quickly. We can improve our estimation ability through practice and study in our daily life. We can practice in different ways, such as doing more oral calculations, looking at the size and shape of things around us, and practicing by estimating time and distance.
3. Master the application method of estimation.
In daily life, we can use estimation methods to solve some practical problems. For example, you can estimate the total price of an order when shopping, and you can also estimate the time and distance required when planning a travel route. By applying the estimation method, we can solve the problem more quickly and accurately and improve our practical application ability.
4. Pay attention to the unit conversion in mathematical estimation.
How to do math estimation in grade three? In mathematical estimation, unit conversion is very important because it will affect the final result. For example, when converting centimeters and meters, we need to divide centimeters by 100 to get the corresponding number of meters.
Step 5 Practice.
Practice is the key to learn mathematical estimation well. In the usual math exercises, let children do math estimation exercises, fully exercise their math thinking and reasoning ability, and help them master math estimation skills.
In a word, when learning math estimation in grade three, we should pay attention to the law of estimation, improve estimation ability and master the application method of estimation. Only in this way can we achieve better results in math learning.
