Understanding area

The topic  is a topic under the 6th Grade Math Mission. This exercise practices visual understanding of area and geometric comparison.

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


 * 1) Identify rectangles with given area: This problem gives the student an area and asks them to identify which of the diagrams in the multiple select list have that area correctly modeled.Ua1.png
 * 2) Compare the area: This problem provides two polygonal regions drawn on a grid. The student is asked to identify which covers more or less squares and this which has more or less area.Ua2.png

Strategies
This problem does not require any special geometric knowledge. Rather it can be performed with understanding of how to count square units, and an ability to manipulate pictures.
 * 1) In order to measure an area with unit squares it is required that the squares are congruent and flush with each other. Also, they must not exceed the figure being measure, nor may the leave any blank space.
 * 2) On the Compare the area problem the answer less will always connect with smaller and more will always connect with bigger. Also, the A shape will always be the benchmark for comparison.
