Estimating length (mm, cm, m, km)

The first instance of  is under the 4th grade (U.S.) Math Mission. This exercise practices estimating the length of real life objects using metric units.

Types of Problems
There is one type of problem in this exercise:


 * 1) Estimate the length: This problem has an object and asks for the mass that is most likely. the student has to use knowledge of the metric unit system of units to arrive at an answer. Estimating length (mm, cm, m, km).PNG

Strategies
This exercise is easy to get accuracy badges as long as user knows the length of basic everyday objects.


 * 1) Common sense is helpful in this exercise (the length of a pencil is cm, not mm ($$\frac{1}{100}$$th of a centimeter).

Real-life Applications

 * 1) Measurements are used for many things, such as cooking, and for placing carpet.
