Dalia made 8 party bags for her birthday party. Each bag contained 4 small gifts for her friends. When Denis said that she could come, Dalia had to make one more bag with 4 gifts. How many small gifts did Dalia need to fill her bags?

Walter wrote this number model: 8 x (4+4)=64

Explain what Walter's mistake.

1 Bag = 4 Gifts

Total # of party bags = 8

Total # of part bags + Denis = 9

So originally the # of gifts without Denis would have the following equation:

8 x 4 = 32

Now that Denis is coming we have 9 party bags:

9 x 4 = 36

OR

(8 x 4) + 4 = 36

So you see that the mistake is where Walter placed his brackets. Does this make sense?
