This activity is a great way to get students comparing, contrasting, and understanding the various properties of quadrilaterals. They drag the properties into the correct vortex. If the answer is correct, the vortex "swallows" the property. If the answer is incorrect, the vortex "rejects" the property. After placing all the properties in the vortex on the particular slide, the slide will show a list of what properties went into each vortex. This is helpful because it gives the students an opportunity to copy down the correct answers.
The quadrilaterals are rectangles, rhombi, square, kite, trapezoid, isosceles trapezoid, and quadrilaterals in general.
The properties include: bisected diagonals, congruent diagonals, congruent opposite sides, diagonals bisect angles, 1 pair of sides are equal, perpendicular diagonals, interior angles that add up to 360, opposite angles equal, diagonals are perpendicular bisectors.
