I know how to actually enlarge the picture of the block but how do you figure out how to make the sizes of all the pieces?
As an example the 6 1/2" block calls for a 1 1/2 x 2 1/2" strip..... does that just become a strip 3x5"?

Lots of people have been giving good answers, but no one has actually answered your question:
"As an example the 6 1/2" block calls for a 1 1/2 x 2 1/2" strip..... does that just become a strip 3x5"?
The answer is "No." They go on to explain why. So 1 1/2 plus 1 1/2 becomes 2 1/2.
And two plus two is not four. It's 3 1/2. And 2 1/2 plus 2 1/2 becomes 4 1/2.
Quilters math? We need to double the base piece without the seam allowance, as others have said.
