Visual Learning: Circles, Triangles and parallelograms

Interactive Powerpoint presentations for any learner but with the visual learner specifically in mind.

Our school curriculum is still very largely print-based, and visual and kinaesthetic learners may have diffculty accessing it. The recitation and the symbols involved in counting and recording with numbers and the routine procedures of calculation are hard to grasp and easy to forget. With the advent of the numeracy strategy, mental images — number lines or the area multiplication method, for example — have become far more common in our classrooms.

But what about shape and space? Surely here we can expect visual and kinaesthetic learners to shine! It depends how the concepts and principles are presented.

What many pupils need is a mental image, a dynamic model on which they can hang their understanding of the crucial concepts. Then they can recall not the value but the image from which the value may be derived. The capacity of Powerpoint to show movement is useful here.

Circumference and Area of a Circle

Two interactive Powerpoint files that present the concepts of circumference and area of a circle and the relationship between them (pi).

Tandi Clausen-May presents a more detailed overview of these presentations in her article ‘Going Round in Circles’ in MT199.
