Chapter: Numbers And Operations
1. Solves multistep mathematical and real-world problems using addition, subtraction, multiplication, and division of rational numbers
Multistep problems involving rational numbers require not only computation but also analytical reasoning and contextual interpretation. Rational numbers encompass all numbers that can be written as a ratio of two integers, including positive and negative whole numbers, fractions, terminating and repeating decimals, and mixed numbers. Students must identify the correct operation for each step in a problem and understand how operations relate to one another, especially in authentic contexts.
a. Identifies different problem situations for the operations (e.g., adding to, taking from, putting together, taking apart, and comparing for subtraction)
Word problems involving rational numbers may be structured in various ways, and recognizing the type of situation guides the operation to be used:
