Our Understanding Addition/Subtraction of Fractions lesson plan teaches students strategies for adding and subtracting fractions with like denominators. During this lesson, students are asked to work collaboratively with a partner to create a poster explaining some of the underlying concepts behind adding and subtracting fractions, solidifying their understanding of the concepts used in this lesson. Students are also asked to solve practice problems in which they have to add or subtract fractions.
At the end of the lesson, students will be able to explain how to add and subtract fractions with like denominators, including how two fractions refer to the same whole.
