Yavuz Samur found mentalup-brain-teasers:

• Significantly improves behaviour or wellbeing“For example, my son is playing MentalUp for a long time and I see that he understands what type of games are good for him. He is able to choose quality games for himself by comparing them with MentalUp.”
• Significantly reduces teacher workload“There are many curriculum integrated activities and practices in MentalUp such as addition, subtraction, multiplication and division. Kids are working on them and increase their math skills. Teachers do not need to work on those skills anymore.”
• Significantly improves teaching efficiency and productivity“As MentalUp also works on short term memory and recalling strategies, in the classroom kids can learn&understand faster and more efficiently. ”
• Does not improve school processes“There is no direct relation between school processes and MentalUp, it is more for students' mental abilities and wellbeing.”
