Order by length

The topic  is a topic under the Early Math Math Mission. This exercise uses lines and lengths to compare relative sizes.

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


 * 1) Order the line lengths: This problem provides three lines of different lengths. The student is expected to use the manipulative to put the lines in decreasing order, largest line segment on top.Obl1.png
 * 2) Use blocks to compare: This problem has two figures that are supposed to be compared by their relative sizes compared to some given blocks. The student is expected to answer a couple questions from a list.Obl2.png

Strategies
This exercise requires geometric knowledge more than algebraic knowledge to be done correctly.
 * 1) The order for the line segments is always largest on top. This can help with speed.
 * 2) Natural intuition can be used to assist on the Use blacks to compare problem, but should not be relied upon. Sometimes it is possible to manipulate the symbols to make things different sizes.
