How to Use Interactive Number Lines for Math

MatholiaChannel

A detailed tutorial demonstrating the features and pedagogical applications of an interactive number line tool for elementary mathematics. The video showcases how digital manipulatives can be used to visualize key concepts including counting, addition, subtraction, and number patterns using customizable intervals and steps. The content explores specific functionalities such as using digital ink to annotate equations, customizing number line variables (start number, intervals, step count), and using interactive 'jump' blocks to model arithmetic operations. It demonstrates how to scaffold learning by hiding or revealing numbers to test student understanding of sequences and patterns. This resource is particularly valuable for teachers and parents looking for effective ways to model abstract math concepts visually. It highlights how technology can support differentiation in math instruction, allowing for real-time customization of problems—from basic counting to more complex skip counting and multi-digit arithmetic—suitable for various learning levels.
