Monopoly is pretty much the worst board game to introduce children to.

Monopoly Deal on the other hand is an excellent game, quick to play (10-15 minutes), works well for 2, 3 or 4 players and the rules are clear and simple. Not to mention how cheap it is, usually less than $5.
Yes, Amazon had it as a stocking-filler a few Christmases ago at $4. The card version is fast and requires no board, so can be played with kids aged 8+, on a restaurant counter/ park bench/ bus/ plane/ whatever. There is a small amount of strategy and remembering what has been dealt, but BoardGameArena rates it easy (complexity 1.3/5).
