Pbs Learning Media: Ccmp8 Part 1 Using Repeated Reasoning

Students are taught to look for patterns in solving mathematical problems. Starting in the lower grades, they learn that math problems can be decomposed and recomposed without its value changing (the distributive property). In these videos, you'll see teachers demonstrating how ratios, percentages, and fractions can have very similar meanings but depending on the context, they might choose one strategy over another. Students can use this knowledge to simplify and solve more difficult mathematical problems in higher grades.
