Its main component was Ca2 (Mn, Mn)[Si O] 2 (Ox) 2. The characteristics of nephrite were as follows: - ** Physical properties **: - ** density and hardness **: The relative density is between 2.80 - 3.10, and the hardness is between 6 - 6.5. - ** Color **: Various colors, white, grayish-white, yellow, yellow-green, gray-green, dark green, dark green, black, etc., translucent to opaque. - ** Quality and Toughness **: The quality is dense and delicate, and the toughness is high.

Building blocks for early childhood education was a very beneficial activity for children. Some of the early education puzzle blocks were written according to Montessori's early childhood education theory and had a variety of playstyles. In the process of assembling, the baby at a younger age could carry out simple operations to promote the development of his ability. For example, the mother could give the baby two blocks to demonstrate knocking. The sound of knocking could attract the baby and promote the development of hand-eye, ear-brain perception ability and fine movement accuracy. After the mother put up the building blocks, the baby pushed down the building blocks, which could train the baby. If the building block packaging was similar to a bucket, it could guide the baby to take the building blocks in and out, cultivate spatial perception, and promote the coordinated development of hand-eye-brain. Older babies can play more complicated games, such as playing with the whole family, stacking high, and taking turns to pull out the wooden strips after the building blocks are stacked high. This will test the baby's observation ability and hand-eye coordination ability while also enhancing the parent-child relationship. If there are different patterns printed on the top of the building blocks, you can play a memory game like flipping the card. First show the pattern, then cover it and adjust the position to let the baby find the pattern in the memory. In addition, there were many other games such as styling, setting up scenes, dominoes, numerical calculation, shape recognition, color recognition, color classification, etc. These games were not only fun, but also could train the baby's creativity, imagination, and memory. For example, some special puzzle building blocks, such as Cachito magnetic pieces, could also play a role in the puzzle enlightenment during the assembly process. Some puzzle building blocks could make the baby have a good understanding of small animals, which involved the improvement of graphic cognition, hand-eye coordination and other aspects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
