DEVELOPING PRE-NUMBER CONCEPTS : Previously you have read how children acquire concepts. You know that, for children to grasp a concept, they must be given several opportunities to explore and experience it. While exploring, they must be encouraged to talk about what they are doing. And, all this requires us to be patient. Some of us start by encouraging children to look for the answer themselves. But when they take time, our impatience makes us give them the answer or do the task quickly ourselves. This prevents the children from reasoning for themselves and finding out.

That is how they will develop their understanding of mathematical concepts and their ability to think mathematically.
