If you take stock of the excellent popular science books on the domestic market that can lead children into the science hall, there is one series that cannot be avoided, that is, the "DK" series of books.
This series comes from DK company Dorling Kindersley, continues to lead the international graphic and document publishing style with its professional content and distinctive visual design. In the eyes of many parents, the DK series of books is the ceiling of popular science children's books, and it even has the reputation of "DK production must be a fine product".
This time, the book "DK Fun Mathematics Laboratory" introduced by Heilongjiang Children's Publishing House also continues its consistent high level. It uses 27 mathematical games in three categories: "number", "shape" and "measurement", to introduce children into the wonderful mathematical world, complete mathematical enlightenment and wisdom enlightenment, and lay a good interest foundation for future mathematical learning.
In the "digital" part, taking " Fibonacci Sequence " as an example. As the top task of the "laboratory", it is definitely to lead the child to complete an experiment. This experiment is " Fibonacci Spiral Collage". The book
first lists the mathematical knowledge needed for this experiment: sequences, proportions, and right angles. If parents have a certain foundation, they can first give their children some relevant content.
also has a finished product rendering, which looks quite artistic:
Next, the book lists the materials and tools required for the experiment, and of course also includes the mathematical tools themselves that need to be used - "Fibonacci Sequence":
Then the "experimental steps". In this experiment, everyone needs to draw squares of varying sizes based on the "Fibonacci Sequence" on the grid coordinate paper. The small reminder like a small calculator often reveals the mathematical principles behind the experimental steps.
As the experimental steps unfold, the finished product of this experiment has taken shape step by step:
Finally, the book will also show young readers the mathematics in the real world, that is, the form of the "Fibonacci sequence" in nature and art. We found that the shape of the scale rehearsed by the scales of pine cones and pineapple is the "Fibonacci spiral" used in the experiment just now, and even the "Fibonacci sequence" is used in Da Vinci's famous painting "Mona Lisa".
After such a mathematical experiment, I believe that children can have a deep impression of the "Fibonacci sequence". What do you think?
In addition to the "Fibonacci Sequence", there are 26 other mathematical experiments in the book. They take the children to learn about a series of mathematical knowledge such as algebra , equations, addition, subtraction, multiplication and division, parallel lines, proportions, coordinates, shapes, density, etc., and can also let children make toys such as "jumping frogs", "three-dimensional greeting cards", "rubber band racing", "shadow puppet", and "color clocks" with their own hands. Isn't it also very fulfilling?
