Quadrilateral types

The first instance of  is under the 4th Grade Math Mission. This exercise practices knowledge of features of different quadrilaterals.

Types of Problems
There are three types of problems in this exercise:


 * 1) Use the picture to determine the quadrilateral: This problem has a quadrilateral drawn and labelled and asks the student to select which of the categories the quadrilateral falls under.Quadpic.png
 * 2) Use the definition: This problem has a sentence with no picture. It asks the student to select answers from the right. The problem either has the type of quadrilateral in the problem and the properties in the answer choices, or vice-versa. The example shows a problem where students select what type of quadrilateral is being described.Quaddef.png
 * 3) Drag into correct category: This problem concentrates on one type of quadrilateral and asks the student to drag examples of that quadrilateral into one box and non-examples into another.Quaddrag.png

Strategies
This exercise is easy to get accuracy badges as long as you are confident with the quadrilateral hierarchy. Speed badges are easy too since even the dragging problems can be done fairly efficiently if you know the definitions.


 * 1) Khan Academy defines a trapezoid as having at least one pair of parallel sides. Therefore a parallelogram IS a trapezoid for previous exercises.
 * 2) With the exception of parallelogram, most answers will involve selecting multiple options.
 * 3) Research indicates that all drag and drop problems are divide with two in one category and three in the other.
 * 4) Because the screen moves downwards as you drag and drop, it seems best to fill the bottom category first if you can.
