Understand a fraction ๐/๐ with a > 1 as a sum of fractions 1/๐.

Decompose a fraction into a sum of fractions with the same denominator in more than one way (e.g., 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8), recording each decomposition by an equation. Justify decompositions by using a visual fraction model.

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

Add and subtract mixed numbers with like denominators by replacing each mixed number with an equivalent fraction and/or by using properties of operations and the relationship between addition and subtraction.

Solve contextual problems involving addition and subtraction of fractions referring to the same whole and having like denominators.

Understand a fraction ๐ข/๐ฃ with ๐ข > 1 as a sum of fractions 1/๐ฃ.

Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
