Mathematics in the second grade
You know, there's a lot of interesting math in this magnificent palace! Today, follow
I'm going to explore it
Let's start with the old palace house. There are so many palaces in the palace, they're like a super-large building
Scramble. You see, these palaces are especially organized, like soldiers in line. There's math in it
Yes! For example, the palace is symmetrical. What's symmetry? Just like mirrors, mirrors you and mirrors
You look exactly the same outside, you look the same on both sides. So does the palace of the palace, which follows the center axis to the left
The buildings on both sides of the right are almost identical. It's in the middle of the middle axis, looking and going to the left
Look on the right, the layout around the building is similar. This symmetrical design makes the palace look very dignified and big
Is it amazing
Look at the doors and windows in the palace. They're mostly rectangular. Rectangular is our math
There are often graphics learned. The rectangular has two long and two short edges, all of which are straight angles. Imagine, like..
The doors and windows are not rectangular, but rather strange
Nice? Besides, the craftsmen have to measure precisely the length and width of these doors and windows
It'll make sure they're well-equipped and sewn。
And there is mathematics in the walls of the palace. A piece of brick was laid on the ground, particularly flat。
Have you noticed that many of these bricks are square? The square is a little like the rectangle, but it's square
All four sides are the same size. The craftsmen laid these square bricks one by one
Play puzzle games and make the whole ground clean. Besides, when laying the bricks, you have to use it
Mathematics, figure out how many bricks it takes to fill up the ground
There's more room, there's less room。
So the math in the palace is like a little treasure waiting for us to find it. Next time, when you're going to visit
When you're in the palace, you can watch and see if you can find more interesting math secrets
