Addition and subtraction within 20 - Subtraction not crossing 10 - Worksheet

Mastering the basics of subtraction within 20 is made engaging with a series of worksheets designed to help children understand and practice the concept without crossing the ten boundary. These educational resources utilise visual aids such as ten frames to represent numbers, offering a hands-on approach to learning. In one activity, children are presented with ten frames filled with images, and they are tasked with crossing out a certain amount to depict subtraction, followed by writing down the calculation. This method helps them visualise the subtractive process and reinforces their numerical understanding.

Another worksheet variation introduces ten frames alongside part-whole models, where children encounter numbers written in words and demonstrate their subtraction skills using both tools. For those ready to challenge themselves further, blank ten frames are provided, prompting students to draw the required amount before subtracting and recording their calculations. Real-world scenarios involving birds, cows, balloons, and apples are used to contextualise the subtraction problems, making the mathematical concept more relatable and easier to grasp. The worksheets are designed to promote fluency and precision in mathematical operations, ensuring that children can confidently subtract numbers within 20 without crossing the ten threshold.
