There is a gap between the current needs of society and the new generations computing knowledge. One of the current challenges is to include learning programming in school. This learning can be done without lectures but through activities in a creative environment. A new software, Scratch allows it. Its junior version of tablet is recommended from 5 years. With this application I tested how far it is possible to offer an introduction to planning of action sequences to pre-school children, before child begin to position itself as a simple user. This experiment aims to measure the learning acquired and test different parameters. It appears that apprenticeships are realized thanks to an unplugged activity, explicit instruction, a creative use of aspects of the software and a continued presence of the adult. The results of this study are only patchy. The sample size and duration of appren-ticeships are too low. Several parameters are tested simultaneously by lack of means. The results would therefore need to be refined.
