Do you know what the signs of learning disabilities are? Probably not because there are no physical signs. On the other hand there are some signs. When a child has trouble reading or writting it could be a sign of having a learning disability. This doesnt mean they are not smart they just have issues understanding a certain subject like history or a math class. Most kids find out they have a learning disability when they can’t follow simple rules or can’t even keep up in a classroom. usually learning disabilities show up in grade school and begin to get worse as the child gets older. Some of the kids can basically hide their disabilities which mean they could possibly not show up till their teen years.
