Primary 4 Mixed Numbers Interactive Visualization
2021-06-27 06:41
This GeoGebra applet is designed for Primary 4 students to interactively explore the concept of mixed numbers. Using rectangular box visual models, students can intuitively understand how a whole number and a proper fraction combine to form a mixed number. The tool features denominator input boxes, add/subtract buttons for dynamic adjustment, and real-time visual updates showing fraction partition
