OverviewIn this learning topic, students will deepen their understanding of fraction relationships, their parts to a whole, and how they compare to other fractions. Expanding on their prior knowledge of least common multiples and greatest common factors, students will compare and simplify related fractions and recognize their equivalency. This is a review of Math 4 standards to help solidify their understanding of these concepts before applying them to the operations of addition, subtraction, multiplication, and division. This also provides an opportunity for students to dig deeper into fraction relationships as they exist in the realworld and how simplify and comparing fractions can help them be more informed of their meaning in context.
