At what age are Kumon Math A materials?
Kumon Arithmetic A is the equivalent level of 6 years old.
From the A level onward, Kumon Math A is designed so that when students advance one letter in the alphabet, they also advance one grade level. Although there are some parts where the grade level and the alphabet diverge somewhat, it is safe to assume that the alphabet basically corresponds to the grade level.
What kind of materials does Kumon Arithmetic A teach?
The aims of the Kumon Math A materials are as follows
Based on the basic addition and subtraction skills acquired up to the 2A materials, Kumon Arithmetic A will help students improve their mental arithmetic skills and move on to the written arithmetic skills of the B materials.
One of the main features of this course is the introduction of subtraction.
Let's take a look at the materials in more detail. Arithmetic A consists of 200 printed pages, and the contents are divided into the following categories.
| Material number | Contents | | | --- | | 1-10 | Toss-up 1 (review of 2A) | | 11-20 | Toss-up 2 (up to 12) | | 21-30 | Toss-up 3 (up to 15) | 31-40 | Toss-up 4 (up to 18) | | 41-50 | Toss-up 5 (up to 20) | | 81-90 | Tip 1 (Tip 1) | 91-100 | Tip 2 (Tip 2) | 101-110 | Tip 3 (Tip 3) | 111-120 | Tip 4 (Tip 3) | 112-121 | Tip 5 (Tip 6) 111-120 | 4 (up to 3) of Hikizan | | 121-130 | 5 (up to 5) of Hikizan | | | 131-140 | 6 (up to 10) of Hikizan | | 141-150 | 7 (up to 11) of Hikizan | | 151-160 | 8 (up to 12) of Hikizan | | 161-170 | 9 (up to 14) of Hikizan 9 (from 14) | | 171-180 | 10 (from 16) | 181-190 | 11 (from 20) | 191-200 | 12 (summary of subtraction)
40% of the material consists of addition and 60% of subtraction. Also, as the material progresses, the numbers handled gradually increase in size.
What are the key points of Kumon Math A?
The key to success in Kumon Math A is to identify + and -.
Addition and subtraction in Kumon Math is more like memorization than understanding.
As mentioned in the article on Kumon Arithmetic 2A, learning addition in Kumon arithmetic is based more on memorization than understanding. Since the material for addition begins in Arithmetic 3A71, students will have solved a cumulative total of 410 addition printouts up to this point. By this point, students will have reached the point where they can almost reflexively answer single-digit addition questions.
Addition and subtraction formulas are almost identical in appearance.
However, if you start solving subtraction as is, confusion will surely ensue. This is because + and - look very similar, and the numbers look exactly the same as in addition. The difference between "3+1=" and "3-1=" is almost like finding a mistake if you don't know what the formula means.
Of course, if your child has progressed this far in his or her studies, it is unlikely that he or she will ever truly understand the meaning of subtraction. However, up to this point, the method of solving addition has been ingrained in their bodies. It will take a certain amount of time to make the switch.
If the confusion intensifies, the addition will be affected. Memorized knowledge is something that will spill out of your head as soon as you lose confidence in it.
Reducing emotional confusion is the key to success.
The key here is to minimize your child's confusion.
It may be difficult to avoid confusion altogether. However, by avoiding greater confusion, you can minimize the impact on addition that your child has already mastered once.
One key to reducing confusion would be for parents to not react to their child's stumbling more than necessary.
At the end of addition, you are solving for an addition that adds up to a maximum total of 28, so you may feel more impatient than necessary when you see your child stumbling over a single-digit subtraction. However, your child may feel the same way. is the same for your child. If you feel more pressure than necessary, you may lose "trust in memory," which is the key to memorization.
Parents definitely understand that the cause of confusion is "the difference between addition and subtraction. By being prepared, parents will be able to minimize emotional upset and respond in a way that does not destroy their child's confidence.
