A few years ago, Chang Dad took the time to choose a circle of teaching aids for Xiao Chang, basically counting the teaching and auxiliary exercise books on the market and buying all the ones that could be bought, so that Chang Dad found out: Now the water of the teaching auxiliary circle is really deep.
First of all, there are too many varieties! In addition to many of the old teaching assistants, there are also various "internet celebrities" and "artifacts" that emerge endlessly, are very popular on various platforms, and are dazzling.
Secondly, the same is the teaching aids, each positioning, usage, question type and question volume are also different, find the right for the child's situation in order to be useful, otherwise it is a waste of the child's time and energy. Therefore, how to choose the most suitable one for your children is also a big knowledge.
School starts soon, Chang Dad has been urged to teach mathematics to supplement the assessment, today finally came to turn in the homework.
(Everyone's enthusiasm, Chang Dad can't help but agree to ah)
In order to ensure that it is as comprehensive and informative as possible, in addition to purchasing a batch of mainstream teaching aids years ago, Chang Dad has specially searched for a circle on the Internet, added more than ten kinds of teaching aids specifically for mathematical calculations, and came to a super full evaluation in one breath!
(Just counting this category is a dozen books, to a big group photo)
Why is there only calculation this time? Chang Dad explained that the mathematics course actually has a lot of specialties, and it is unlikely that an article will be clear. The reason why calculation is chosen to take the lead is because calculation is the lifeblood of mathematics and the foundation of the foundation -
The more important reason is that I have already written thousands of words in just one calculation! (Desperate face)
So for everyone, to be able to come in today is to earn.
Today first say calculation ha!
Calculations, no matter how much emphasis can not be overemphasized
Calculation is the foundation of mathematical ability. Especially after the double subtraction, more attention is paid to the examination of computing power. In the final exam just past, in the mathematics examination paper of a certain district in Beijing, there were 22 points in the simple calculation questions, accounting for nearly 1/4 of the scaled score.
Moreover, the calculation question has always been said to be "sending points", and the calculation questions should be all correct in the exam. But in fact, many children have made "sending questions" into "sending propositions", which is the reason why the calculation is not solid. What's more, in addition to pure calculation questions, all aspects of a mathematical test paper are inseparable from calculation, and calculation errors will affect the overall score.
In addition, in the long run, when the child enters the senior grade, the amount and difficulty of the test paper have risen, and only by ensuring the calculation speed can there be enough time to think about the final big question. Moreover, many people will overlook that the physical chemistry to be learned in junior high school also has a lot of calculations waiting for children!
Therefore, the computing power is not good, and the mathematical physics and chemistry are all pulled. And there is a very realistic problem is that for the application of mathematics, as well as the big problems in physical chemistry, it is difficult to have the idea of understanding the problem, a pass operation is as fierce as a tiger, but because the number is wrong, the result is all wasted, and the result of this problem will not be the same, just ask you if you are wronged?!
So, the calculation must be practiced! The accuracy of the calculation is all practiced, and all the mistakes that seem to be carelessly made are actually not practiced enough, and the hands and brain are too rusty.
However, there is also good news here: as long as you practice calculation scientifically and persistently, you will definitely see results! It doesn't depend on whether the child is smart or not, but on how much effort is put in.
For practice, there is no other trick, can only take out 10 minutes a few times a day, in a rich form of special practice of calculation (especially for primary school children, especially to avoid boredom). And the calculation should be based on what the child has learned, including oral arithmetic, vertical calculation, off-style calculation, simple calculation and other problem types.
In the past, I was not very interested in the teaching aids of the calculation special project, thinking that they were all the same, but this time I dug deeply, to be honest, the general books will be really difficult to enter my eyes in the future.
Some of the windy teaching aids
Under the fame, it is actually difficult to match
As mentioned earlier, in addition to some classic teaching aids, Chang Dad also bought back some of the "hot selling" teaching aids on the recent network. I really don't know, I am really disappointed to see it, I have to give the fans a wake-up call before the official evaluation: don't just look at the wind, but don't polish your eyes, don't mess into the pit.
For example, this oral arithmetic question card, known as the "universal version", has nothing to do with the progress of the textbook, and children across the country can use it. I bought a look, the original direct extraction of the two under the 4 calculation plates, each plate out of a few pages of questions, combined together to finish. This "general version" is a bit sloppy to look at.
(This is a directory of oral arithmetic question cards, which is really quite convenient)
And each page is copied and pasted, the first 8 lines are directly written to count, the last 17 lines are filled in the blanks, the topic design does not have any gradient, back and forth are similar. What's more is the mixed operation, each article is the same, I don't know that I think it is a typographical error, there are a few second-grade children who can insist on brushing this book, I am also convinced.
(There is no eye halo, every page is the same)
There is also a book that claims to use it to "punch in for 10 minutes a day, punch for 100 consecutive days, and calculate 100 points for children." Some bloggers will also accompany the child's punch card video to reflect the effect when they bring the goods. However, looking closely at this topic, I really can't help but scrutinize it for 5 minutes.
For example, the whole division is a key learning section in the second grade, but in this set of oral arithmetic problems, only the first 5 pages contain all the divisions in the table, and then it is even removed, copy and paste the same as 6 page questions, and the division is finished. There is no step-by-step difficulty gradient, the amount of key questions examined is not enough, if you really take it to punch, it is estimated that many children will be planted on this 6th day, and then be wronged by their parents is the child who does not know how to insist?
(Day 5 or simple division, day 6 even removed?) This punch card gradient is also too big)
The content arrangement is also under consideration, dense and dense, and it is a headache to see.
(This question, again like copy and paste)
Some people may see here and think that Chang Dad is too critical, isn't the oral arithmetic book like this, well, I used to think so, but the mainstream oral arithmetic books on the market are almost bought, after reading better, I still have the courage to say this.
Next, according to the use scenarios of different children, let's talk about how to choose reliable computing teaching aids, and how to use them to make faster and more efficient progress.
The Basics:
Weak calculations often go wrong
A score of B or 85 or less on the exam
Several cases where the computing foundation is weak may be due to little practice and slow speed, or it may be that the concept is not clear, often miscalculated, or it may be that the writing is not standardized, and the mistake of writing misalignment is always made. The next few sets of teaching aids, each set for different situations, see which set is suitable for your own children!
Standardize writing, oral arithmetic and pen calculation together
"Sunshine Classmate Calculation Little Master"
Editions: Renjiao edition, Beishida edition, Sujiao edition
"Calculation Master" closely follows the progress of the school, in addition to the clear table of contents, but also refines each page to the number of pages of the corresponding textbook. Intimately, the font size is also the largest of several similar teaching aids I bought, and the children do not hurt their eyes when they use it. In addition to oral calculation, vertical calculation has also been added to the question type.
The oral calculation part, usually 40-50 questions, also clarifies the time for the completion of the suggestions, which is convenient for children to pinch time to practice speed. When parents give their children corrections, they can directly take pictures and correct them, without having to calculate them one by one, saving time and energy.
Look at the vertical calculation: each page is usually 6 questions, the most intimate point is to give a dotted line, to help children standardize writing, which is really useful. Many children write irregularly, either the vertical is too close to the horizontal and squeezed together; or the two numbers are not aligned with the upper and lower digits; or they are crooked and twisted together.
(Small vertical bar to help children standardize writing, super useful)
From the arrangement of the whole book, in addition to daily exercises, each knowledge module also has stage exercises, collation and review, mind maps of the entire unit, as well as special exercises and unit calculation detection of error-prone questions. It can be said that it is more systematic, and it helps children lay a good foundation for calculation in an all-round way.
To sum up, this book is suitable for children with weak foundations, especially those who write irregularly. Oral arithmetic and vertical style can be practiced, the difficulty of the topic is not high, for children with weak foundations, they will have a sense of competence and are willing to cooperate to do it.
Based on the foundation and then improve, the number of questions is larger and more types
《Primary School Oral Arithmetic Clearance》
If "Little Master of Computing" is a proper basic model, this set of books is based on the foundation and then raised. I don't know how elsewhere, at least in the Beijing parent circle, the reputation of "Oral Calculation" is very good, and the user base is also very extensive.
Basic positioning, oral arithmetic and pen calculation together, each problem has time suggestions, these common points Chang Dad will not repeat, mainly talk about the differences.
The first is that there are more questions per page, in addition to oral and pen calculations, there are also fill-in-the-blank questions.
(Oral arithmetic pen calculation together)
The second is that the question types on each page of "Oral Arithmetic Clearance" are more diversified. Take the knowledge point of "chartering a ship" twice, in addition to the conventional oral arithmetic, there are two "divisions with remainders" related error correction questions. Because the application of the charter type of boat, how many boats must appear? There are still a few people left and other problems, and the division of the remainder will definitely be used, and there will be such a question in the "Oral Calculation Pass".
For example, in the knowledge point of "measurement", there will be 6 questions about unit conversion. Similarly, there are also some comparison sizes, filling in forms, connecting a variety of question types.
(Each unit will also have a special algorithm combing mind map)
To sum up, this book has a higher gradient in the basic teaching aids, invisibly more demanding on children, and spends more time every day.
Advanced:
The calculation is not bad, improve the sprint
Test score A or above 85
The child's foundation is OK, do you still need to take time to practice calculation every day? Chang Dad feels that learning is also a marching style, every day should maintain the feel, if the knowledge points recently learned and calculation is not too much to do (such as geometry), it is still necessary to insist on doing calculation problems.
But if the recent new lessons are all about calculations, then it is more important to do the homework well, internalize the calculation methods, and then decide whether to brush the calculation workbook specifically according to your own situation to improve your proficiency.
The questions are diverse, and the feel is maintained for 10 minutes a day
"Computing Expert"
Compared with the previously recommended books, this set of calculations is first of all moderately difficult, so it is also suitable for children who want to raise.
Take the pen math, the same is the second unit of the first unit of the practice problem, "Calculation Master" is the addition and subtraction of two numbers, and "Calculation Master" is all three numbers of addition and subtraction, but also with parentheses, the difficulty is significantly increased,
The second point is that the question types are more abundant, there are fill-in-the-blank calculations, there are comparative calculations, as well as applied calculations, regular questions and so on.
In use, seven days a week are arranged, basically 10 minutes is enough, the weekend volume is a little larger, 20 minutes is almost, for children with a good foundation, there is no burden.
(Children can do it according to the rhythm, more worry-free)
The topics are difficult to distinguish and can be used flexibly
Intensive Training on Mathematical Calculation Problems in Primary Schools of Weekly Plan
Version: Universal Edition
The "Weekly Plan" series of East China University of Science and Technology Press is very famous, but the difficulty is not small. The calculation book is also full of intermediate and above difficulty questions to avoid children repeating them at low levels (but not over-the-top). The topic is very typical, and it is also divided into stars.
For example, the knowledge point of "addition and subtraction of heterogeneous denominators" in the fifth grade, from one star to four stars, the gradient is set very well.
In this way, children are very flexible when using this set of books. If you have enough time, you can do it in the order of the book arrangement, and you will certainly not suffer losses. But if you are tight on time, or if the child's own foundation is very solid, there is no problem with one star and two stars, you can use your time to do three-star and four-star problems.
In terms of the arrangement of the books, this set is divided according to the grade, one for each grade, although it is all in the syllabus, but does not completely follow the teaching progress, but according to the math module.
(This is a catalog of fifth-grade math)
In the design of the questions, a lot of thought has been spent on helping children train systematically according to the question types. For example, in the multiplication law section on the five, there are 4 pages dedicated to the simple method that are systematically trained, and the difficulty gradually climbs. While other books may involve easy methods, this set of books is modular, using classic questions to do systematic exercises.
(There are 4 pages of different question types and angles to help children practice simple calculations)
Speaking of this, everyone also understands this set of books: the requirements are relatively high, the use is more flexible, suitable for children who are medium-high, have a solid foundation, and want to continue to raise points.
We say that mathematical calculations are very important, the foundation of the foundation, and the emphasis should be paid, but it is not necessary to go to the extreme and spend too much energy, and take 10 minutes a day to keep practicing. After all, this is a long-term practice process, and the best strategy is to be lightweight, long-term, and the right medicine.
In addition, if the family already has a calculation class of teaching aids, do not waste money to buy new, first use the ones at hand, if you just need calculation problems, then I hope that today's article can help you save time and energy in selection, you can find the calculation teaching aids suitable for children faster.
