mentions puzzle games, the first reaction of many people may be "tangram"
is so popular with tangram, that is because the benefits of playing tangram are really countless: exercise hand-eye coordination, identify colors, practice graphic segmentation and composition , To cultivate observation, spatial imagination and logical thinking skills...

However, for a baby who only has three minutes of heat, he will get bored soon. (Silent distressed my money bag o(╥﹏╥)o)
In addition to tangrams, building blocks, etc., what other easy , and puzzle games? "Overlapping Reasoning Game" is a good choice!
What is an overlapping game? Give a simple example:
Please carefully observe the circles, squares and triangles in the figure below. Do you know which figure is at the front and which is at the back?
Judging the top and bottom order of the stacked graphics is the most common form of overlapping games. Although the game like looks simple, there is actually 's rigorous logic behind it, , which should not be underestimated!
Next, let’s talk with you in detail: how can play overlapping games step by step, so as to improve children's spatial imagination and logical thinking ability.
The magical "overlap" phenomenon
"overlap" is not only a concept in mathematics, it is also a common phenomenon in life.
For preschool children, if they have not seen overlap in their daily lives, will naturally not understand the meaning of overlap, and they will not be able to abstract the appearance of two or more overlapping patterns in the brain.
Taking advantage of summer, mom and dad might as well ask their children when wear sunglasses : " do you see any changes in my eyes? "

Here I recommend a picture book "Little Yellow and Little Blue" , which also contains There is a lot of overlapping content, but this overlap is extended to the overlapping of colors.
start from the dotted line overlap
dotted line overlap is the basis of graphic overlap.
Let’s start with the overlap of points and try to determine which of the three triangles below is on the top and which is on the bottom?
believe that the first reaction of many people will be: these three triangles are in the same plane. But in fact, if you carefully observe the color of their overlapping points, can tell the clues.
For example, the color of the overlapping vertices of the red triangle and the blue triangle is blue, so the blue triangle should be on top of the red triangle.
and the color of the vertices where the yellow triangle and the blue triangle overlap is yellow, which means that the yellow triangle is above the blue triangle.
while the lineThe overlap is similar to the overlap of points, can be judged by the color of the overlap between lines .
is still these three triangles, now you come to to judge their positional relationship?
compare the three triangles overlapping line segment color , it is easy to get their up and down order:
If the child can't understand well, you can use the cotton swab or swing stick around you to let him know. The overlap of
is also fun.
After mastering the overlap of dots and lines, you can play the overlap of graphics.
Mom and dad need to prepare two transparent plastic sheets of the same size (or file bag) in advance , pastes interesting stickers on different positions of the two transparent sheets, is as follows:
Try to ask the child, 4z After the two cards are translated and overlapped, what kind of picture will
can let the child guess, and then describe it.
In this process, we need to guide children to understand: after overlaps, the elements on each card will not change.
There is a tree and a round of sun on the original card, they still exist after overlap; the original small tree is in the lower left corner and the sun is in the upper right corner, then their relative positions will not change after overlaps
may as well let the children do it by themselves and see what kind of results they will get!
If the card A is rotated 180 degrees clockwise and then overlapped with the card B, it will have higher requirements for children's observation and sense of space.
Let the child think about it first, and think about what A will look like after being rotated. What happens when A and B overlap?
Finally, make a swing, and you will find that the sun and the small tree overlap each other!
Observe the overlap of multiple objects
Let's take the overlap of three objects as an example.
Please carefully observe the three figures in the figure below. Which figure is in the front and which figure is in the back of ?
We can guide children to think in three steps:
① Of the three figures, only the blue semicircle can be seen by us, while the yellow trapezoid and the red diamond are in front of the blue semicircle, which is blocked.
② Through observation, we can also find that in addition to being partially blocked by the trapezoid, the diamond is also blocked by the semicircle, while the trapezoid is only blocked by the semicircle.
③ Therefore, we can draw the conclusion: semicircle is at the front, the middle is trapezoid, and the last is rhombus.
dad and mom can cut out several different color graphics from the color cardboard at home and place them in different ways. let the children observe and tell who is in front and who is behind.
When judging the overlap phenomenon, children can also understand various graphics and be familiar with Their characteristics are . The overlapping content of
seems simple, so it is easy to be overlooked by parents. I hope today’s sharing can inspire you.
Cultivate children's various thinking, parents need to start from the little bit of life, when the child's thinking ability reaches a certain level, the "miracle" you expect will really appear.
