An important concept of mathematics is the ability to interpret the size and volume of something with respect to another. The pre-number concept of big and small was thus introduced through fun-filled activities that encouraged learning by doing in class. Learning through participation is an effective way to make the concept interesting and enjoyable learning without boredom. Preschool children are very observant and this trait can be put to use to introduce new concepts to them. Thus child centric and activity based methodologies are designed to encourage learning in children.
After a child understands about different sizes, he or she is able to understand about other similar concepts like lesser than, greater than, larger than, smaller than, and equal to or the same as. Such stimuli are precursors to developing mathematical, sequential, analytical and logical thinking in children.
