Ten problems to a page, printed large, with plenty of space around each one. This is for a student with low vision, or one whose handwriting is still developing and needs room to form the digits - the same maths as the standard sheet, drawn bigger.
Large print is size and spacing, not a special typeface. A dyslexia-friendly font is a common request, but the evidence that it beats a plain sans-serif at a larger size is thin, and a larger size is exactly what this page gives you. Adjust the number ranges and operations below as usual.
Students with low vision, and younger students whose fine motor control is not yet up to writing small digits. It is also a common accommodation on an IEP.
You can, but the point is few and large. Ten fills the page at this size; going higher shrinks the digits back down.
No. The research does not clearly show one helps over an ordinary font at a larger size, and this page already gives you the larger size. If a font is added for another reason it would apply here too.
Yes - the key is printed at the same size and spacing as the worksheet, so it is just as easy to read.
