Measuring area with unit squares

The first instance of  is under the 3rd Grade Math Mission. This exercise explores the concept of area specifically using square units and unit squares.

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


 * 1) Find area of striped region: This problem has a grid drawn and the student is expected to find the area of the striped region by counting how many unit squares are striped.Area1.png
 * 2) Find area of the shape: Although this problem is also shaded/colored this shape is drawn on a grid and seems to encourage the student to find the correct area by subdividing a shape into easier shapes rather than just counting.Area2.png

Strategies
This exercise is medium to get accuracy badges because the interface makes it east to miscount the dimensions of the shapes. Speed badges are hard because of the time needed to be careful and get the right counts.


 * 1) In the first problem type, you can count the number of shaded squares in each row easier than dimensions, so you can use this ability to count the total slightly faster.
