Thus, the first grade students were able to help one another correct the weaknesses in their own approaches by discussing their ideas with their classmates, and were able to solve the problem. The children actually expressed a lot of ideas that mathematics tries to teach as they spoke naturally about what was going on during this activity.
The role of the teacher is to organize these concepts and make student aware of them. I have actually conducted research on lessons that focus on the children's "first responses" that occurred during this activity (Hiroshi Tanaka (2001)). Two of the typical words that came up were ''for example,'" and "if,'' words that lead to generalizations. After he phrase "for example,'' the child would express their own specific "way of understanding" the issue. When a child wants to convey something they understand to their friends in an easy-to-understand way, using specific scenarios. The word "if' is used when one wants to make a generalization" by thinking about a development, changing the conditions, or providing a counterexample. These are also words that cultivate skills of inductive inference, a typical form of reasoning
