Use yourself for "I" and the student for "you".

     

Let's say you had 8 pennies. I gave you 4 more. How many pennies would you have altogether?
(8 + 4 = ?)

     

Let's say you had 7 pennies. I gave you some more. Now you have 13 pennies. How many did I give you?
(7 + ? = 13)

     

Let's say you had some pennies. I gave you 6 more. Now you have 15 pennies. How many did you have?
(? + 6 = 15)

     
Separate      
Let's say you had 11pennies. You gave 5 pennies to me. How many pennies do you have now?
(11 - 5 = ?)
     
Let's say you had 12 pennies. You gave some to me. Now you have 9 pennies. How many did you give to me?      
Let's say you had some pennies. You gave 5 to me. Now you have 9 pennies left. How many pennies did you have to start/begin with?      
Part-part whole      

Let's say you have 5 pennies and 10 nickels. How many coins would you have?
(5 + 10 = ?)

     

Let's say you have 13 coins.. Five coins are pennies and the rest are nickels. How many nickels do you have?

     
Compare      

Let's say you have 11 pennies and I have 8 pennies. How many more pennies would you have than I would? (11 - 8 = ? or 8 + ? = 11)

     

Let's say you have 13 pennies and I have 9 pennies. How many fewer pennies would I have than you?
