When you see a fraction, you see a numerator and a denominator. To find the common factor, see whichever number among these is least: The numerator, the denominator or the difference between numerator and denominator.
Reducing fractions is another skill involved in just about any of the fraction operations. The fraction worksheets on this page introduce reducing gradually by providing problems with increasingly more difficult denominators, and only gradually introducing mixed numbers and improper fractions.
Subtracting fractions is similar to adding fractions. Most of the work involves the denominator. If the denominators of the two fractions are already the same, much of the work is done. Simply subtract the two numerators to get the answer fraction using the same denominator, and then reduce and make a proper fraction.
Get some addition practice while reading picture books together. There are a ton of great picture books that have overt and hidden addition facts and practice, but you can turn any book into a lesson in addition. If you read a page with a picture of a forest, you might say to your child, "I see three trees and four flowers. How many plants are there all together?" You can add characters, shapes, items, or anything in multiples.
