# Now Picture a Zillion Cupcakes…

February 21, 2018

You might not believe this, but that South Africa flag is made of cupcakes! This record-breaking picture used 33,600 cupcakes, and covered almost 1,500 square feet (imagine a 1-foot-wide square on the floor…then imagine 1,500 of those). Pictures that are made of lots of tiny dots or pieces are called “mosaics.” Think of the math it takes to make a giant one. You have to figure out how much of your big picture uses each color, based on the small picture you’re copying.  You have to lay out your colors — in this case, cupcakes — in straight rows of the same length. And if you messed up in the middle, you can’t just walk over there to fix it: you have to take out all the cupcakes in your path. When that happens, you might as well just sit down and eat!

Wee ones: The bottom of a cupcake is a circle. Find 4 circles in your room.

Little kids: If you place 2 rows of cupcakes with 3 cupcakes in each row, how many cupcakes have you placed?  Bonus: If half of them have white vanilla frosting, how many vanillas do you have?

Big kids: If you place cupcakes in 6 rows of 6, how many do you have?  Bonus: How many of those cupcakes are NOT touching an edge of the square?

The sky’s the limit: If you have 60 cupcakes, how many ways can you arrange them in a rectangular picture with equal length rows and at least 2 cupcakes in any direction?

Wee ones: Items might include a button, a shoelace hole, the rim of a cup or glass, or clocks.

Little kids: 6 cupcakes.  Bonus: If half of them have white vanilla frosting, how many vanillas do you have?

Big kids: 36 cupcakes.  Bonus: 16, since the edges outline a 4 x 4 square in the middle.

The sky’s the limit:  There are 10 ways to line them up:
2 rows of 30 cupcakes each
3 rows of 20 each
4 rows of 15 each
5 rows of 12 each
6 rows of 10 each
…and then the rotation of each of those (10 rows of 6 each, 12 rows of 5 each, etc.).
