Lesson Plan Description
This Fifth Grade, fully scripted half day of Math lesson plans is broken up into 3 separate segments (30-60 minutes each). These lessons address Numbers and Operations- Fractions: adding and subtracting fractions and mixed numbers with unlike denominators (5.NF.A1). 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 basic 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 add/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.
