    Measure the objects and compare

Strategies

This exercise is easy to get accuracy badges because the measurements are short and the ruler is placed well. The amount of questions that need to be answered make this hard difficulty for speed badges.

  1. Do not move the ruler. It is in the ideal place to begin with.
  2. Users can just see the length of the first object and the second and use this information to answer all four questions without having to refer to the picture again. Remembering the four answers after seeing the initial lengths can increase their speed a little bit anyway.

Real-life Applications

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