Addition Year 4 - PowerPoint

In this Year 4 maths lesson, students will enhance their addition skills by learning to add numbers with up to four digits using the column method. The lesson introduces the concept by focusing on the importance of place value when adding and subtracting using written methods. Students are shown how to align numbers in columns according to their place value, ensuring that units, tens, hundreds, and thousands are in the correct columns before proceeding with the addition.

The lesson continues with a step-by-step guide on using the column method to add numbers, starting with the least significant digit (the ones column) and moving towards the most significant (the thousands column). For example, students are taught to add the ones first, then the tens, followed by the hundreds, and finally the thousands, carrying over any extra tens as necessary. The lesson also introduces a more efficient strategy known as the compact method, which simplifies the process by eliminating the need to write zeros to hold places and by carrying over tens with a simple notation. Students are then given a series of calculations to practice this method, with the aim of becoming proficient in column addition and developing their numerical fluency.
