When Trouble With Math Equals a Learning Disability(1/2)

So far in our series on learning disabilities we have talked about problems with reading, writing and movement. Today we talk about a problem that affects the brain's ability to process and understand the meaning of numbers. The name for this is dyscalculia. Children with dyscalculia have trouble reading numbers and picturing them in their mind. For example, they might mistake a three for an eight because the numbers look similar. They also have trouble counting objects and organizing them by size.

Memory is another issue. Children with dyscalculia may not remember the correct order of operations to follow in solving math problems. Difficulties like these can lead to a lifelong fear of mathematics.

Of course, just because people have trouble with math does not necessarily mean they have dyscalculia. But experts say parents and teachers may begin to suspect a problem if a child is good at speaking, reading and writing but slow to develop math skills.

Does a child remember printed words but not numbers? Does the child have trouble making sense of time or understanding the order of events, like yesterday, today and tomorrow?

参考译文:

到目前为止,关于学习障碍我们已经谈了阅读、写作和运动方面的问题。今天我们谈的问题是影响大脑处理和理解数字含义方面的问题。这个称之为计算障碍。患有计算障碍症的孩子在读数和记住数字方面有困难。比如,他们会将3误看为8因为这两个数字相像。他们也在数数和在按大小组合物品时存在困难。

记忆力是另一个问题。患有计算障碍症的孩子可能无法记住数学运算的正确顺序来解决数学问题。类似这样的困难会让他们对数学产生终生的恐惧。

当然,仅仅因为一个人在数学上有困难并代表他患有计算障碍。但是专家称,如果孩子很擅长读写说,但是在数学技能上发展缓慢,父母和老师可以开始怀疑这个儿童是否患有该病。

是否您的孩子可以记住单词但是无法记住数字?是否孩子在理解时间的意义,以及了解像昨天、今天和明天这样的事件顺序方面存在困难?
