Alone, each of these types are effective but when combined, they can dramatically improve the effectiveness of the presentation, Multimedia design include a video capture, video editing, sound editing, photograph scanning and editing, logo digitization, morphing, creation of 2D and 3D models, and animation. I think multimedia mode of teaching in association with class room teaching would help students to understand complex math problems easily. It must be user friendly Interaction with users must be very easy Regular feedback about extent of success should be provided Sound should be soothing, mild level of music is better Presentation of problem should consider the difficulty level of your students There must be some gradation in generation of math. For elementary level, it is better to view math as some patterns. So teach your students at this level to discriminate the patterns, e.g. 3,4,5,6.
Child can discriminate the patterns through specific attributes of the figure.
Tell them to classify those figures from different perspectives. The logic for classi fication is important for math skill development. After classification of figures or objects, try to understand his importance on specific perspectives. Next you select another problem so that other perspective can be accounted to classify the assigned objects. For example, give him some buttons with different sizes and ask him to classify them.
