How to draw the tree of mathematical wisdom in the first volume of the seventh grade
A concrete way to draw the tree of mathematical knowledge in the first volume of the seventh grade is to draw a tree diagram, and then you can write the name of each knowledge point on the distribution of branches and leaves. If you look at it on the basis of graphics and geometry, you can use two points of three-dimensional graphics or plane graphics as two main branches.

Then, on a specific branch, we can know the geometry, unfolding and folding of the three-dimensional figure in life, and look at the shape of the object from three directions as a classification, and then write it on the whole tree of wisdom. There must be a specific connection between the branches and leaves of the tree of wisdom.

In other words, such a connection can be described by a wisdom book, so the first book of the seventh grade mathematical wisdom tree can be drawn like this.
