1, let children skip the number of physical objects and directly enter the abstract thinking ability, just like the attic in the air, which is getting bigger and crumbling. Take the child of figure 1 as an example. If you ask him why his child is 35 15, the child must not know. This simple method of learning mathematics by rote, like my little niece, will not be carried out until the problem becomes more difficult and there is a turning point. Some parents, in order to enlighten their children in mathematics, read "12345" in their mouths when they climb the stairs with their children; Many children can count from one to one hundred when counting, which is basically a memory method. If children can't see the "number" of specific objects, they can eat professional knowledge by memory at first, or they can fill it by hard work. In high school, the knowledge points are mixed with each other, which is difficult and will be enough soon.
2. The number in the object is the "number" that children can see with their eyes. Compared with other popular and non-mainstream classroom teaching for girls, Montessori teaching has an obvious advantage: children play basic mathematics very well. In the teaching process of Montessori kindergarten, what attracted my most attention was a string of colored beads in the math class area, which were composed of 1, 10, 100 and 1000 respectively. Children can count the total number of beads one by one through their own visual touch, and then gradually touch more numbers and cubes from shallow to deep. After a long time, the child can see the approximate number of this pile of beads and that bead at a glance.
This is the "number" that children can see. For children, this will be a number and a valuable number. There is no room for children to put math teaching AIDS in the classroom of parent-child early education (and Montessori teaching AIDS are expensive). You can buy some beads online, wear them on the wall from 1 and hang them on the wall. Count and play with the children.
3. When teaching children math class, they should also take out the physical objects to teach in class. 10 simple addition and subtraction, teaching tools can be beads or sticks. Many parents and children like counting their fingers. First of all, this special tool can be used at any time and anywhere. Another one, you can use it immediately, without looking for other special tools from your schoolbag. Although fingers are the same special tool, I don't recommend parents to use them for their children. There is no other reason, because children often forget the other hand after counting one hand. For example, 6+4, children always make mistakes when counting their fingers. The root cause is that children make mistakes and rarely make mistakes when counting sticks and beads.
When the child vividly sees how the beads below 10 are added and subtracted, he will gradually find that 4 is originally composed of 2 and 2, or a combination of 1 and 3; 5 was originally a combination of 1 and 4, or a combination of 2 and 3, or a combination of 1 and 1 and 3, and a combination of 2 and 2 and 1. At this time, it can be said that the child saw the secret of mathematics. For every child, this discovery must be happy and accompanied by satisfaction.
Mastering ten digits is a related event. In this process, children are likely to spend a long time on membership. What parents need to do is be patient and give their children time to explore and think for themselves. Because once children under 10 are mastered, the time from 10 to 100 can be greatly shortened.
