How to Make More S’mores

How to Make More S’mores

May 16, 2019

S’mores bring together two really yummy treats: chocolate and marshmallow. You roast a marshmallow on a stick over a campfire, then smush it with a square of chocolate between two graham crackers. The hot marshmallow melts the chocolate into a gooey, tasty mess. Well, two ladies at Gooseberry Patch show us how to bake a whole tray of S’mores at once. You layer chocolate squares and mini-marshmallows on top of graham crackers, then bake the whole thing at 400 degrees. It makes 16 melted S’mores just like “real” ones, and without any leaves or dirt mixed in!

Wee ones: If S’mores use graham cracker, chocolate, and marshmallow, how many ingredients do they use?

S'mores trayLittle kids: If your S’more uses 2 crackers, 3 squares of oozing chocolate, and 2 gooey mini marshmallows, how many pieces do you use?  Bonus: If you make a super tall S’more that layers cracker, chocolate, marshmallow, then cracker again to repeat…what’s the 12th layer? 

Big kids: If your tray holds 4 rows of 6 crackers each, how many S’mores can you make at once?  Bonus: If each S’more uses 3 chocolate rectangles and you have 7 bars of 8 rectangles each, do you have enough rectangles to make 20 S’mores?

The sky’s the limit: To find out if a number is a multiple of 7, you chop off the last digit, double it, then subtract that from what’s left of the number. If you get a multiple of 7 (including zero and negative multiples of 7) as your answer, then the starting number is a multiple. If each S’more uses 7 mini marshmallows and you have a bag of 196 minis, will you have any leftover minis as you make your S’mores?

Wee ones: 3 ingredients.

Little kids: 7 pieces. Bonus: Marshmallow, just like every 3rd layer.

Big kids: 24 s’mores. Bonus: Not quite. You’ll need 60 pieces, and the bars give you only 56.

The sky’s the limit: No leftovers — 196 is a multiple of 7! To test 196, you chop off the 6 to leave you with 19. Then subtract 6 x 2 (which is 12) from that 19. This gives you 7, so 196 will let you make an exact numbers of S’mores.
