Hannah received a wooden house puzzle as a gift and enjoyed putting together the different shaped pieces. The document then discusses quadrilaterals, including defining them as polygons with four sides and angles that sum to 360 degrees. It provides examples of different types of quadrilaterals like squares and rectangles. Mike wants to build a robot out of quadrilaterals since he can't afford a toy robot.
