This product is a useful tool for helping students who have trouble adding and subtraction fractions with unlike denominators.

Log in to see state-specific standards (only available in the US).
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, 𝘒/𝘣 + 𝘀/π˜₯ = (𝘒π˜₯ + 𝘣𝘀)/𝘣π˜₯.)
Understand a multiple of 𝘒/𝘣 as a multiple of 1/𝘣, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 Γ— (2/5) as 6 Γ— (1/5), recognizing this product as 6/5. (In general, 𝘯 Γ— (𝘒/𝘣) = (𝘯 Γ— 𝘒)/𝘣.)
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
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. Examples: 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.
