There's a tendency to think that verbal and mathematical reasoning might be things that aren't problematic for multilingual learners, but in fact they can be especially when we translate mathematical language into English language or we have children verbalize it or try to use verbal skills to solve the problem. How so, well look at this:

What day follows the day before yesterday if two days from now will be Sunday?

If I ask a monolingual learner this question, is the answer immediate available? No. You've got to work through that. Imagine the difficulties in comprehension a multilingual learner might have if they aren't proficient in English as a monolingual learner. Or, in comparison to their same age, same grade peers. It is difficult. And if you want to know what the answer is, well the answer is Thursday. Why? Because today is Friday and two days from now will be Sunday. That means the day before yesterday was not Thursday, but Wednesday. And the day that follows Wednesday is Thursday. 

Here's another example:

Paul makes $25.00 a week less than the sum of what Fred and Carl together make. Carl's weekly income would be triple Steven's if he made $50.00 more a week. Paul makes $285.00 a week and Steven makes $75.00 a week. How much does Fred make?

If you are reading this and wondering, "Who is Fred and where did he come from?" imagine how multilingual learners are challenged by trying to translate mathematical concepts into language that they are not nearly as proficient. They have to recognize words like less than, the sum of, together, and triple. These are things that will cause a great difficulty to multilingual learners. While we think sometimes that reasoning is just reasoning, when language is introduced into the equation it's going to make it even more difficult for our typical English learners.
