This is a music video about what parallelograms are. Examples are shown of parallelograms during the informative song. The song has rhymes that can, potentially, help students remember the attributes of parallelograms. (01:40)

This is video about parallelograms narrated by students. The video asks the question, what makes a parallelogram? This is suitable for third grade. Examples are shown on a white board. (0:50)

Tim Bedley, veteran teacher, gives a mini lesson to remind students how to identify a parallelogram. A parallelogram has 4 sides that are parallel and parallel. The teacher uses a interactive board to decide whether shapes presented or parallelograms... or not. This is a great resource to introduce and/or to review parallelograms in the elementary and middle school classroom. (1:42)[more]

This video gives a Parallelogram Definition: A quadrilateral with two pairs of parallel sides. Squares, rectangles and rhombi are parallelograms. Trapezoids and kites are not. The opposite sides of a parallelogram are congruent and the opposite angl...es of a parallelogram are congruent The consecutive angles of a parallelogram are supplementary. The diagonals of a parallelogram bisect each other. The diagonals of a rectangle are congruent, like those of an isosceles trapezoid. The diagonals of a rhombus are perpendicular, like those of a kite. (03:42)[more]

Lesson on rhombuses, parallelograms, and traezoids. This lesson is an introduction to these figures that come up in geometry. Larry explains figures on a white board. More lessons at: http://www.MathWithLarry.com

Students learn the definition of a parallelogram, which states that if a quadrilateral is a parallelogram, then opposite sides are parallel. Students also learn the following theorems related to parallelograms. If a quadrilateral is a parallelogram, ...then opposite sides are congruent. If a quadrilateral is a parallelogram, then opposite angles are congruent. If a quadrilateral is a parallelogram, then the diagonals bisect each other. Students are then asked to solve problems related to the properties of parallelograms using Algebra.[more]
