Today we solved a problem - draw on a geoboard paper a polygon with four dots on the sides of the polygon. Many gave quadrilaterals. Students were encouraged to draw figures other than quadrilaterals.
After finding the area of a few figures, a conjecture was made - figures with fours dots on the sides and none inside has an area of one.
This led to a discussion on instructional model for teaching problem solving.
