Lesson Plan Description
This half day of lesson plans is broken down into 3 separate segments (30-60 minutes each) addressing Numbers and Operations- Fractions: adding and subtracting fractions and mixed numbers unlike denominators. Students will learn key fraction vocabulary, take helpful notes for reference, complete independent practice of concepts and play a game to reinforce the concept of adding and subtracting fractions with unlike denominators.
Segment 1: students will add and subtract fractions with unlike denominators using both a bar model and multiplication.
Segment 2: students will add and subtract mixed numbers with unlike denominators using both a bar model and multiplication.
Segment 3: students will demonstrate their understanding of the above-mentioned concepts through playing a game requiring them to either add or subtract fractions with unlike denominators and then compare the sums or differences.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
