💡 How to Use This Worksheet

This worksheet is designed to reinforce the concept of column subtraction with exchange for Year 3 students. Before using this worksheet, ensure students have a solid understanding of place value (hundreds, tens, and ones) and basic subtraction facts. Begin by reviewing an example of column subtraction with exchange on the whiteboard, emphasizing the process of borrowing from the next column when the digit being subtracted is larger than the digit it's being subtracted from. Encourage students to clearly write out their calculations, showing the exchange process by crossing out the original digit and writing the new digit above it. Monitor students as they work, providing support and guidance where needed. After completion, review the answers as a class, discussing any common errors and reinforcing the correct method.
