This resource focuses on teaching students how to manage and solve numerical expressions involving the addition and subtraction of integers, specifically in the context of a bank account balance. The document outlines several steps, beginning with a worked example of a bank account scenario where students start with a negative balance, make a deposit, and then withdraw funds. Step-by-step guidance is provided in the form of practice problems to help students calculate 'net change' after each transaction. It includes visual aids, such as number lines, for better understanding, a section for error analysis to address common misconceptions, and an independent exercise to solidify mastery of integer operations. The resource encourages critical thinking regarding absolute values and their application in real-world contexts, offering a well-rounded approach to understanding integer changes in monetary situations.
