Addition and Subtraction - Subtract a three digit number from a three digit number (no exchange) - Worksheet

Mastering subtraction without borrowing is a key skill for young learners, and this set of worksheets focuses on subtracting three-digit numbers from other three-digit numbers without the need for exchanging. The National Curriculum objective is to add and subtract numbers mentally, including three-digit numbers with ones, tens, and hundreds, as well as using formal columnar subtraction methods. To facilitate the learning process, a range of resources are provided, including differentiated sheets, teaching slides, number lines, and Base 10 blocks.

The worksheets are designed to help children understand and apply various subtraction strategies such as counting on using number lines, near subtraction, and number bonds. They also practice laying out calculations in a formal column format, supported by visual aids. Throughout the activities, children are encouraged to think critically about the methods they choose and to check their answers for accuracy. The tasks include solving problems like finding the number of boys at a disco when the total number of children and the number of girls are known, as well as practical scenarios such as a greengrocer calculating his remaining stock after giving some away. This approach not only reinforces mathematical concepts but also connects them to real-world situations.
