How do you use do and does for kids?

Could you please elaborate on how you might use the words 'do' and 'does' when teaching young children about language and grammar? Perhaps you could provide some examples of sentences or activities that help kids understand the difference between the two words and how to use them correctly in a sentence. Additionally, could you discuss any challenges or misconceptions that might arise when teaching these concepts to young learners, and how you might address them?
