Explanation:

According to my research on studies conducted on children's learning capabilities, I can say that based on the information provided within the question these children tend to perform poorly on formal math tests. This is because children who grow up in the streets, learn what is called Street Smarts. This gives them the ability to perform well in everyday math scenarios such as giving change and counting inventory for a store, etc, but they do not fair so well in formal tests because they do not have the training or experience.
