I use a different method. I told my daughter to name it so that she
would think of it as her own. She called it the "ten and minus method"
Here it is:

34-18  
1.  so get the 18 to the nearest multiple of ten which her is 20. So
we added 2

2. From 20 to 30 is 10
    and to 34 it is 10+4 which is 14

3. 14+2 = 16
