what is sequence of development
the difference between sequence of development and rate of development and why is the difference important. speed at which development happen. The difference is important because speed does not necessarily have to do with the sequence also it's important to recognize the difference so you can identify where children need help or at risk.
Rate and sequence of development vary due to nutrition and the environment. In addition some skills are genetic in nature. As a result, there is a range of normal for development.
The order in which development happens e.g. walking before running.
Prenatal development occurs in three main stages: the germinal stage (first two weeks after conception), the embryonic stage (weeks 3-8), and the fetal stage (weeks 9-birth). During these stages, the fertilized egg undergoes cell division, differentiation, and organ formation, leading to the development of a fetus.

Because they can only predict what they have saw and experienced so far and not everyone is the same therefore they may have a diffrent sequence of development
how and why variation occur in the rate and sequence ot develpment and learning

Well.... The difference is purely the names. They are completely identical.
