Multi-step Addition and Subtraction Problems - PowerPoint

In a comprehensive PowerPoint presentation aimed at Year 5 students, the focus is on developing skills to tackle multi-step addition and subtraction problems. The slides guide students through a series of steps to effectively solve complex numerical problems. Initially, students are encouraged to read questions carefully, underline key vocabulary and information, and understand what the question is asking. This approach is applied to a practical example involving concert ticket sales, where students must calculate the total number of attendees after considering tickets sold in advance, on the day, and accounting for no-shows.

The presentation further explores the use of bar models as a visual aid to solve multi-step problems. One such problem involves three friends who have collected a total of 840 shells, with relationships defined between the quantities each friend has collected. Students use bar models to divide the total number of shells and calculate individual shares. The PowerPoint also includes a variety of scenarios, such as posting Christmas presents, reading pages in a book, and a postman's deliveries, each requiring a combination of addition and subtraction to solve. These real-world examples are designed to engage students and enhance their problem-solving abilities in a relatable context.
