Measure lengths 1

The first instance of  is under the Early Math Math Mission. This exercise introduces the use of ruler-like objects to measure one dimensional attributes of objects.

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


 * 1) Squares as ruler: This problem uses squares to act as a measuring device. The student is to look at the picture and count how many squares long it is.Ml1-1.png
 * 2) Correct use of ruler: This problem has a collection of three pictures that use squares to measure the length of an object, but only one picture uses the squares correctly. The student is to select the correct picture and give the correct length.Ml1-2.png

Strategies
This exercise is easy to get accuracy badges on because the none of the lengths are very long. Because of the time it takes to count some of the longer pictures, getting speed badges should be considered medium.


 * 1) It might ease measurement if you make a ruler, but this would rely on all squares in all problems being identical which has not been verified.
