The worksheet focuses on enhancing children's fluency and precision in adding two three-digit numbers, particularly when the addition involves crossing tens or hundreds. The National Curriculum objective for this lesson is to solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction. The resources provided for this lesson include differentiated sheets and teaching slides, which cater to varying levels of student ability. The vocabulary for the lesson includes terms such as 'add and subtract' and 'column method,' which are crucial to understanding the process of addition with exchanges.

During the lesson, children learn to add two three-digit numbers, starting with scenarios that require a single exchange and progressing to more complex situations involving exchanges in two different columns. To aid comprehension, students may use Base 10 or place value counters to visually represent their calculations. It's important for students to also practice the written method, ensuring they grasp when and why an exchange is necessary. The lesson includes key questions that probe students' understanding of the exchange process and its application in solving problems. By the end of the lesson, children will have worked through independent activities using place value grids, part-whole, and bar models, with the difficulty level adjusted to match their understanding, from working towards the expected level to achieving greater depth.
