What educators are saying

My students loved this and found it really helpful. Breaking down the steps really helped. Do you have something like this for adding/subtracting fractions?
This was a great way to reteach this skill and it provided good independent practice for students as well! The representation of the process was extremely helpful!

Description

Learning Least Common Multiples (LCM) and Least Common Denominator (LCD) can be challenging, especially when students need to add and subtract fractions with unlike denominators. These worksheets contain instructions, tables and templates to help students solve problems with adding and subtracting fractions with unlike denominators.

Teachers can use these pages and a packet-like format, as the worksheets start simple and become more complex with a reduction of supports to help students gain independence. The worksheets start with understanding multiples, specifically the least common multiple among two numbers. The worksheets then move onto comparing fractions with unlike denominators. Students will need to find the least common denominator in order to compare with greater than, less than, or equal to (>,<,=). The next set of pages includes adding fractions with unlike denominators and subtracting with unlike denominators. Worksheets do not require simplifying fractions, as there are some answers that are improper fractions.

Here is what you will receive with this product-

  • 3 worksheets with finding least common multiples (LCM)
  • 9 worksheets with comparing fractions with unlike denominators
  • 4 worksheets with adding fractions with unlike denominators
  • 4 worksheets with subtracting fractions with unlike denominators
  • 5 worksheets with mixed adding and subtracting fractions with unlike denominators
  • 4 how-to worksheets that show examples and explain how to solve the problems
  • 22 answer key pages

Standards

to see state-specific standards (only available in the US).
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
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, 𝘢/𝘣 + 𝘤/𝘥 = (𝘢𝘥 + 𝘣𝘤)/𝘣𝘥.)
