Droite graduée play online

49 very progressive games to place a number on a number line.
Some levels are challenges with record breaking, others are training with progressive help. Finally, there are "survival" type games where the child has a few seconds to find the required number.

To make this activity fun, the program assigns 10 for each exact number, then a decreasing number of points like in archery.
At the end, the star system allows everyone to understand their level of success.
