I have a little book called Collins Carb Counter, but I usually just count from memory or use the info on the packet. When I was first diagnosed, the dietician gave me a very, very useful booklet with carb values in for everyday foods so I was able to learn those quickly.
For pasta, if you know the dry weight carb amount, you can weigh that out (eg 50g dry weight is 35g carbs or whatever) cook it, then weigh the cooked pasta (eg your now cooked pasta weighs 95g so you now know that 95g cooked pasta will be 35g carbs). Then each time you cook pasta for the family, you can simply weigh out the portion for your daughter after its cooked, and you will know the carbs from your previous cooking.
Most pasta is similar for carbs so I don't do that with different brands as they're all very alike. I do have some gluten free pasta and that's higher in carbs so for something like that I would do the above again.
Rice I measure cooked in tablespoons. Potatoes I weigh uncooked. Cereal and flour I weigh.
If you have a recipe, work out the total carbs from the ingredients, then divide it by the portion your daughter is having. What I do then, is write that info on the recipe so if I make it again I know the carbs eg 1/4 is 45g carbs.
It will get easier as you get more experience
