Making bar graph model 3d, in this course introduces students to a creative way of learning data visualization by building a three-dimensional bar graph. In this course, learners explore how numerical data can be represented visually through bars of varying heights or lengths, making complex information easier to understand. Step-by-step guidance is provided on designing and constructing the 3D model using simple materials such as cardboard, colored paper, foam, or wooden blocks. Students learn how to label axes, scale data properly, and highlight comparisons between different values. By building the model, learners not only understand the mathematical concept of bar graphs but also improve their analytical and presentation skills. The course encourages creativity, critical thinking, and hands-on learning, showing how graphs are used in science, economics, and daily life to interpret information. Ideal for school projects, exhibitions, and competitions, this course makes math and science engaging, practical, and interactive for students. howtofunda
