Skew *Quadrilateral* -- from Wolfram It’s such a good task that I didn’t want the small size to affect the kids’ engagement with it in any way, so I recreated the whole handout from scratch using Geometer’s Sketchpad.

A four-sided __quadrilateral__ not contained in a plane. The lines connecting the midpoints of opposite sides of a skew __quadrilateral__ intersect and bisect.

How Do You Find Values for Variables in I did not tell my kids this.[2/8/13: Our geometry textbook defines a kite as a non-rhombus anyway.] My kids not only thought it was fun to form the requested **quadrilateral** given one segment and make it the largest possible area, they also found it challenging to find the area of each shape.

How Do You Find Values for Variables in the Angles of a *Quadrilateral* To Make it a Parallelogram?

Midpoints of Sides of a __Quadrilateral__ Strategy: Students may solve these **problems** in many ways, but this organized approach is most effective and easily replicated by students in the future.

Students are asked to prove that the *quadrilateral* formed by connecting the midpoints of the sides of a given *quadrilateral* is a parallelogram.

Working on these *problems* will help you develop a better understanding of fractions, decimals, percentages and ratio.

Fun Kids Online Math Games - Sheppard Software Math When you're given a **quadrilateral** with some of the interior angles defined with variables, you can find what values those variables need to have to make that **quadrilateral** a parallelogram.

Free online kids math games make learning fun. Topics addition, subtraction, multiplication, division, fractions, money, algebra, and place value.

Don Steward’s Complete the I’ve only learned of Don’s MEDIAN site more recently, and it’s a treasure trove because nearly every post can be an instant lesson in itself. I like this set of 24 __problems__ a lot, but when I click on the image of the __problem__ in his post, I get an image that is too small to fit on paper.
