Here's another one:
Start by putting your game
piece on the 31...
Now, move down
4 places (since it's
-4)...
Just like you'd do on a board game if you got a penalty and had to
go back 4:
We land on the
27...
Yeah, you're still counting down...
But, if you practice this a lot, you'll soon be jumping back 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!
For practice on this, check out
The Number Monster for
great yardstick problems.
