Yes — "two" is an early sight word taught alongside counting. Its "w" is completely silent, and it sounds identical to "to" and "too", so it must be recognized visually rather than sounded out.

"Two", "to", and "too" are all pronounced the same way but spelled differently and mean completely different things — a classic set of homophones. Because sound alone can't tell them apart, children learn to recognize each spelling by sight and connect it to its specific meaning (the number two, versus direction, versus "also").
Practice all three homophones together — two, to, too — using a picture for each (the number 2, an arrow, a plus sign) so the different meanings stay visually distinct.
