Common Words - uncommon ideas

I have been working with students struggling to figure out word problems.

For the most part, the "math" in terms of computation is not the problem. Their problem seems to be making sense of the problem, seeing the relationships between the numbers, and looking at a real world model.

These are kids who can give you 1/2 a dollar and cut a pie in half. They readily distribute half the papers to each group.

They can even tell you that Joe has twice as many pencils as Mary.

But they draw a blank when confronted with a problem of the form x is twice as large as y or even worse x is twice a number.

To think about... what is there in the wording that makes this translation difficult?
