Addition, Subtraction, Multiplication and Division - Add and Subtract Integers - Presentation

The presentation on adding and subtracting integers is a comprehensive exploration of basic arithmetic operations within the curriculum for Year 6 students. The lesson starts with a discussion on what integers are, followed by various activities that challenge the students to perform addition and subtraction with these numbers. The exercises range from simple calculations with single-digit integers to more complex problems involving larger numbers and real-life scenarios, such as calculating the cost difference between houses of different sizes. The presentation's slides guide students through the process, providing structured methods like the column method and encouraging mental arithmetic where appropriate.

One of the key learning points addressed in the presentation is understanding what happens when the sum in a place value column exceeds 10, prompting the need for carrying over or borrowing during addition or subtraction, respectively. The presentation also includes activities where students calculate missing digits, reinforcing their understanding of the inverse relationship between addition and subtraction. Furthermore, it encourages students to discuss and reflect on the efficiency of different methods, such as when it is more suitable to use mental methods over the column method. The lesson culminates with independent work where students solve word problems and deduce missing digits, applying their knowledge in varied contexts.
