The worksheet is designed for primary students to master basic arithmetic operations by visualizing the process of jumping backward in increments of one from a starting integer. The document includes a clear set of problems, followed by a comprehensive answer key to facilitate self-assessment and guided learning. It serves as an effective tool for classroom instruction or home practice to strengthen computational fluency and understanding of numerical sequences. Through repetitive application on a number line, learners develop spatial awareness of number positions and improve their speed and accuracy in performing mental subtraction tasks involving two-digit numbers. This sheet is part of a series intended to support fundamental mathematical skill
