Action verbs in French

At the preschool age, kids are very egocentric and like to talk about themselves. What you can do instead of teaching your kids how to conjugate verbs, is to just teach them a lot of verbs using the first person singular "I/Je". Later on then you can introduce "You/Tu" and the other ones.

Here is a great list of French action verbs to get you started:
I walk - je marche
I go - je vais
I am - je suis
I do - je fais
I sleep - je dors
I want - je veux
I have - j’ai
I dance - je danse
