Comparing numbers to 10

The first instance of the Comparing groups through 10 exercise is under the Early Math Math Mission. This exercise helps students to compares numbers geometrically and associate that with the numerical representations.

Types of problems
There are two types of problems that show up in this exercise:
 * 1) Larger from two pictures: This problem shows two collections of objects. The student is to select which collections has more objects, or if the collections of the objects actually have the same size.Compare.png
 * 2) Count then tell which is larger: This problem asks the student to count the number of objects from two collections, enter them in blanks, then compare to tell which collection is larger.Compcount.png

Strategies
These problems take some care and cannot be done very quickly. They are not difficult if you know how to count up to 10, but patience is needed. They are easy to get accuracy badges, but not easy to get speed badges at this time.


 * 1) In the first problem type the sizes of different objects are different, sometimes significantly. Thus you cannot rely on the image extending further to say that a certain collection has more objects.
 * 2) Collections are generally grouped nicely, allowing counting by grouping strategies.
