Yes, it's an idiom which means 'have a secret idea or plan that you intend to use later' or 'have a surprise plan or solution (to a problem)'.

You may have something good or bad in your sleeve, for example, you may try to cheat by having a card hidden in your sleeve:)  I hope you have something great for a puzzling problem or a situation, though. 

You could write a short paragraph by using the idiom - it can be fun if you really get the picture. Here's a sample paragraph for you:

I'm waiting for Expector's monthly blog challenge. It's time for him to come up with one or he should have published one for us to write a challenge blog, but somehow he's failed to do so this month. He may have something up his sleeve - are you ready for a surprise? 

So, you see, you don't need to write something lengthy - a short paragraph will do. Don't forget to add the 'correction' tag if you really want to be corrected in public - some people may feel so embarrassed or even offended when they're corrected. 

Your turn...

'get the picture' = 'understand something'

  • Dear Expector! It is a great challenge! And your example related to  cards is very right. I would never think up anything better. Playing cards, especially pocker, we always tell a winner "Have you had a joker or a few aces in your sleeve?" If learners like, I will help you correct their mistakes. Thank you!
