Here's another one:

18+6

Start by putting your game piece on the 18...

Yardstick with a game piece on the 18

Now, move up 6 places (since it's +6)...  Just like you'd do on a board game if you rolled a 6 on the dice:

Yardstick with the game piece moving from the 18 up 6 places to the 24

We land on the 24...  

So, 18+6=24

Yeah, you're still counting up...  But, if you practice this a lot, you'll soon be jumping up in chunks.

It won't be long before you start to see the answer up in your head!  Why?  Because you'll see the yardstick up in your head and you'll just be able to THINK about the numbers!
