How much do your kids look forward to your grocery store visits? They will have some fun with this store worksheet. In the printout, the owner of the grocery store needs to know how much food she has left at the end of a busy day. Instruct your kids that they are to help her subtract what she has sold from how much she originally had, in order to figure out how much the store owner has now. Help them read the equations in the picture and solve them to know what the store owner has now.
