1, first put a square with four corners facing up, down, left and right respectively.

2. Put a small triangle in the upper left corner of the square. The upper left side of the square is connected with the short side of the small triangle, and the long side of the small triangle faces left.

3. Place another small triangle next to the upper right corner of the square. The upper right side of the square is connected with the short side of another small triangle, and the long side of the other small triangle faces upward.

Put a big triangle next to the lower corner of the square, and its long side faces right.

5. Put another big triangle next to the long side on the right side of the big triangle, and the long sides of the two big triangles are relatively connected.

6. Place a middle triangle next to the short side of the lower right side of another big triangle. The short side on the left side of the middle triangle is connected with the lower part of the short side on the right lower side of another big triangle, and the long side of the middle triangle faces down.

7. Place a parallelogram next to the right short side of the middle triangle. The left short side of the parallelogram is connected with the lower part of the right short side of the middle triangle, and the acute angle of the parallelogram at the connection is upward.

The benefits of playing jigsaw puzzles:

Infiltrating the knowledge of plane geometry will help children deepen their understanding of graphics in the process of playing, and he will be better than other children in the overall graphics segmentation ability. As long as children start playing jigsaw puzzles and play to a certain extent, as long as they see the figures, they will naturally and reasonably divide them, which will be of great help to their later learning of mathematical geometry knowledge.
