Grayson knits 17 squares on Thursday. He knits 5 more squares each day from Friday through Saturday. How many squares does Grayson have in all by the end of the day on Saturday?
27 squares because both Friday and Saturday he knits 5 squares, if you add them together you will get 10 squares. Then you have to add the 10 squares to the original 17 squares he made.
