I like teaching children Hebrew.
First task: help them get familar with the shape of the letters – and what better way then getting a text and letting them look at it closely.
So I pick the creation account in Genesis 1:1-2:3 and ask the sorts of questions they might be able to do:
How many words are there in the first verse? 7
How many letters? 28
How many times can you see the word ‘God’ appear in this passage? 35
Any chance that the number 7 might be significant in this passage?
