Difficulty: Ⅱ (the first stage of enlightenment)
Suitable age: 4-5 years old (not earlier than 3 years old)
Teaching aid 1: red and blue counting stick
The red and blue digital stick is a Montessori teaching aid, which consists of ten red and blue wooden sticks, each of which is one unit longer than the previous one. With the digital card, the baby can see the change of quantity very intuitively.
When operating, ask the children to pick up the sticks representing 1 and compare them one by one to see if each one is more than the last one.
Children will have more perceptual knowledge of quantity through touch.
Younger children can only know three sticks at a time, and then slowly increase until they know them all. The bigger ones can be more, 3-5 at a time.
First of all, we must ensure that the children operate in order. After getting familiar with it, there are actually more advanced ways to play, such as making up ten.
Montessori education system has many professional and strict requirements for the operation of teaching AIDS, but after all, we are not teachers and have no such professional training. Teaching AIDS may play a more "toy" role in our hands and children's hands.
In the children's hands, this is a toy, and nothing can be made:
I think parents can let their children play freely and feel the change of the number of sticks with different lengths during the play.
Of course, this is just an example. We don't need to buy this teaching aid. In fact, with reference to this teaching aid, parents can make use of existing resources to make similar teaching AIDS.
Such as splicing or building blocks:
Teaching aid 2: colored beaded ladder
This is also a Montessori teaching aid, which consists of 9 strings of beads of different colors, each with one more bead than the previous one. Similar to the function of several sticks, it is much smaller and more colorful.
We can also cut a piece of "counting beads" with a paper shell, which is convenient for children to count beads one by one with their small hands.
This teaching aid can also have many expanded ways of playing, so I won't go into details.
Teaching aid 3: digital sand table
The main function of this Montessori teaching aid is to help children know digital fonts. The figures on the sand table have gone up. Children can print the numbers from 0 to 9 on the sand table with paper and crayons.
Some children are addicted to this "work" because rubbing is a magical and fulfilling thing for them, which is much more interesting than literacy.
When you think that your child knows all the numbers 1 to 10, new problems arise, and the numbers are often reversed.
The numbers in the "Numbers and Chips" in Montessori's teaching AIDS can help children figure out the direction of the correct font:
These wooden figures are painted with two coats of paint, so you can put them anywhere. Getting them to give the correct figures is actually quite a challenge.
Please keep your parents calm when:
Inverting numbers is not your baby's exclusive "problem", but a "common problem" for children all over the world.
There is no unified and absolute explanation for this problem, but the scientific community generally believes that this is the only way to develop children's visual space ability.
Therefore, this is not a reading or writing disorder. Let's help children change it slowly.
Finally, I recommend a mathematical enlightenment "artifact"-playing cards.
Poker has both quantity, order and grouping scheme of quantity (decomposition of number), and has various playing methods, and has the attributes of toys and teaching AIDS. It is really a rare tool for mathematics enlightenment.
As for the playing method of playing cards, you can start with cognition at first, then you can play a few points to compare the size, and you can also play "seven rows" and "ten supplements" slowly.
The specific gameplay will be discussed in detail later.
No matter what kind of teaching aid you use, don't forget to emphasize the concept of the set of numbers to your children, that is, the last number you count represents the set of items.
This is the difficulty in understanding the cardinality and calculation basis.
For the understanding of the number represented by numbers, only a few teaching AIDS are far from enough.
Fortunately, the "props" that can bring quantity perception are everywhere, and there are many in every kitchen, such as peanuts, beans, pots and pans, and even flour and water.
It is necessary to consciously let children feel and understand the changes in quantity through visual stimulation and tactile perception.
Because for children, it is easy to forget what they have heard, but it is easier to remember what they have seen. They will internalize what they have done.
