Adding And Subtracting Fractions Standards. Students also add and subtract fractions with like denominators (4.nf.3) and multiply a fraction by a whole number (4.nf.4), work which they will rely on in this and the next unit. It’s important to show students how to use visual models in addition to the standard algorithm.

The two new fractions should have the same denominator, making them easy to add or subtract. Add the whole number of two fractions separately. Subtracting fractions with different denominators.
In 4Th Grade, Students Mostly Work On Adding And Subtracting Fractions With Like Denominators.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions. (in general, a/b + c/d = (ad + bc)/bd.) Before we can subtract, we'll have to change our fractions so they have the same denominator.
