I need to create very simple games for kids age 4-10

Hi, I need to create very simple games, that I could customize, for kids aged 4-10. These could be memo test games, soccer penalties, and very simple games. They are meant to be operated by a single adult, with the verbal participation of the kids only (i.e.: the kids have to tell a number on the screen and the adult should press it from the laptop. The games will be played in birthdays and important events, in an event room with a giant screen.
