易于测量 / 由盒子做的尺子


This is a simple learning appliance designed for poor areas. making use of an easily available resource -- cardboard boxes. The part of the carton that does not bear the weight is selected for cutting. At the same time, the triangular sawtooth is used for segmentation, which is not only easy to take out, but also can measure the required data more accurately. So that children in poor areas no longer because of the lack of measurement tools affect their learning.
