This document provides a lesson plan for teaching 6th grade students how to add and subtract simple fractions and mixed numbers without regrouping. It includes objectives, instructions, examples, and practice problems. It aims to help students understand how to find the least common denominator of fractions, then add or subtract the numerators and write the answer over the common denominator or as a mixed number. Students are provided examples like adding 3/4 and 1/2, then given practice problems to solve on their own. The lesson plan is designed to help students master the key steps for adding and subtracting similar fractions.

How do we add or subtract dissimilar fractions without regrouping?
REMEMBER!
To add or subtract dissimilar fractions without regrouping:
• Change dissimilar fractions to similar fractions before adding/subtracting
them.
• Add/Subtract numerators. Write the sum/difference over the common
denominator.
• With mixed forms, add/subtract the fractions first, then the whole numbers.
• Add/Subtract the results.
• Reduce to lowest terms when needed.
