| Research Abstract |
We theoretically and practically examined the phase of guess that become important in constructing inquiry-based lesson of mathematics. The results were following.(1) The importance of diagrammatic reasoning and algebraic reasoning.(2) Clarification of the phase of guess and didactical implications.(3) The effectiveness of lesson from the viewpoint of diagrammatic reasoning.
