What are the math experiments in the fifth grade of primary school?
The math experiment in the fifth grade of primary school is mainly a jigsaw puzzle, and then the volume of a chopstick is measured and some graphics are spliced on the paper.

If you use a jigsaw puzzle, many people will know about it, because sometimes when you put together a jigsaw puzzle, you can put together a complete figure with one more piece and one less piece.

Calculating the volume of a chopstick requires more tools, that is, a chopstick, a measuring cylinder, a certain amount of water, a scale and so on. , that is, using the scale difference to calculate the volume of chopsticks.

Because it is not so convenient to directly calculate the volume of chopsticks, it is necessary to use the water level difference to calculate the volume of chopsticks. Then drawing and splicing on paper is the simplest experiment, that is, splicing various geometric figures to make a mathematical experiment.
