Addition and Subtraction - Adding 2 three digit numbers (exchange) - Worksheet

The worksheet provided is a comprehensive resource for teaching Year 6 students how to add two three-digit numbers, including scenarios that require exchanging (carrying over). The National Curriculum objective for this lesson is to solve problems using number facts, place value, and complex addition and subtraction. Students are encouraged to use the column method for addition, and they may also utilise Base 10 or place value counters to visually represent their calculations. The worksheet is designed to progressively challenge the students, starting with single exchanges and moving on to problems that require exchanges in multiple columns.

Key questions focus on understanding the exchange process: how many ones make a ten, how many tens make a hundred, and applying this knowledge to calculate scores in a game scenario involving two characters, Eva and Ron. The importance of accurately showing the exchanged digits in the column method is emphasised to ensure clarity in the calculation process. The worksheet also includes reasoning and problem-solving questions that cater to different levels of understanding, from working towards the expected level to achieving greater depth. These questions challenge students to apply their addition skills to real-world contexts and encourage them to explain their reasoning, thus deepening their comprehension of the mathematical concepts involved.
