—— Mathematics characteristic homework of Class Four, Grade One, Xiangyang Primary School, Hua County.

Tangram, also known as Tangram and Wisdom Board, is an intellectual toy circulated among the people in China. It evolved from the "Swallow Chicken Map" in the Song Dynasty. It was originally an indoor game of ancient literati, and later it evolved into a folk jigsaw puzzle. Now the jigsaw puzzle is cut from a square into seven planar figures, which can be put together into various figures.

The children in Grade One have known the five shapes of plane graphics as a whole, and realized the fun brought by graphic transformation. After further perceiving the relationship between plane figures through hands-on operation and jigsaw puzzles, I arranged a creative and distinctive assignment for students-Rubik's Cube Tangram. The purpose is to let students connect graphics with objects through puzzles and paintings, so that students can feel the division and synthesis of graphics, so as to exercise children's observation, imagination, morphological analysis and creativity, so that children can form a positive and happy emotional experience, so that the learning process can grow and be infiltrated scientifically.

Task:

1. Tangram consists of () graphic boards, and there are () kinds of graphic boards, including () triangles, () squares and () parallelograms.

2. Use your brains and imagination to spell out different patterns with puzzles, stick them on cardboard or cut them on cardboard, and paint them so that the patterns can be integrated into the painting and endowed with artistic conception. Finally, try to give your work a creative name.

Come on, kids!

The operation results show that:

The children have great potential, and their homework amazed me! Give your child a stage, and your child will give you a wonderful stage!
