Abstract
The role of the working memory is important in the processing of multiplication tables; evidently, certain learning methods for children with difficulties in processing them could reduce load on working memory. It is obvious that such learning methods that do not require dependence on working memory are important for the children with a weak working memory capacity. By the combination of working memory and obstacle properties, I made it a type of consideration and the support that were necessary for the multiplication table. As a result, being divided into four types became very clear. In considering support for children with ADHD and ASD, it was found that in learning the multiplication tables, three viewpoints are important. The first is the learning method that I made use of a good point in. The second is security of the learning depending on a characteristic. The third is the prevention of the mistake in the multiplication table for attention and concentration．
