Agree with Antje77. All digestable carbs are digested to glucose and therefore need to be included when you're counting carbs. On that basis, I'd put those crackers in my "avoid at all costs" category (I aim for around 20g/day). At five and a half grams per cracker that's too much carb for me for such a small item.
Depending on your aimed-for daily intake, you might be able to find room.
