Other than a SPAM: alert that may be provided by your email software, how can you tell this message isn't real?

Good Day,

You can use the tracking number with the tracking site below to track the ATM Card to be sure it has been delivered to Mr Hart for activation.

You are to contact Mr Hart with his email address above then he will guide you on how your Card will be activated and delivered to your home address.

Before sending in $280 to activate this card, how can you check its validity? Here are some Red Flags:

On the surface,

Too good to be true: Experience teaches that few things in life are free.
It costs something: Be wary when a stranger asks for money.
It sounds complicated: Why would the IMF send a card to someone else at IMF that you have to contact? Why not just send you the card?

Below the surface,

Sender: If you look closely at the sender's email address you'll find this: "International Monetary Fund (IMF)" info@sender.org.   IMF actually uses this email: @imf.org, which can be found on their Website.  
No Data Found: If you look up whois.net registration information for sender.org, you won't find any. It appears to be a smoke screen.
Third Party Review: Copy the first phrase of the email: "My name is Mrs Linda Walker and I work with the International Monetary Fund (IMF)" and google it. There is an exact match from antifraudintl.org › Scam Mail Depot › Government scams.

There may be more Red Flags, but it's clear that this is not going to result in your receipt of an ATM card.

Have students identify Red Flags -- what others can they find?
