# Secret Chocolate Fraction Codes

It is Post-Halloween and we are not quite finished making chocolate FUN just yet! Here is a fun and easy fractions game to organize that is low-cost and easily teachable, any time of the year.

**Supplies:**

- Crayola Markers, 3 for each student
- One Organic Chocolate Bar for each student
- Piece of Paper

Have everyone bring in a Whole Chocolate Bar (organic if possible – it is healthier!) – One that has an equal number of squares in it. They do not all have to be the same number of squares, but if they are, it is a bit easier for instructions.

Using a non-toxic marker (*Crayola* is my favorite), have each Learner draw a gridline across the paper on the outside of the bar in their favorite color. http://www.crayola.com/products/list.cfm?categories=MARKERS,BASICS

**Step 1:** Counting 1-12 (usually, this is the number of squares in a bar.) If it is different, then ask the learner to count, respectively re their bar, and write down on paper the basic 12 fractions of their bar:

1/12, 2/12, 3/12, 4/12, 5/12, 6/12, 7/12, 8/12, 9/12, 10/12, 11/12, 12/12

**Step 2:** Then *secretly* and individually, each student colors a different amount of squares in each bar, using 3 different colored markers. Encourage Sharing/Trading markers if there is not enough markers to go around.

**Step 3:** Then, everyone divides into pairs, and one at a time – without showing each other what they have colored – each student guesses what 3 numbered fractions the other one has colored.

Eg/ Susan colored 3 squares in Red, 2 squares in Yellow, and 7 squares in Purple. Therefore, Susan’s Secret Fraction Codes are:

3/12, 2/12 and 7/12.

Bob colored 3 squares in Blue, 6 squares in Green, and 3 Squares in Orange. Therefore, Bob’s Secret Fraction Codes are:

3/12, 6/12 and 3/12.

**Step 4:** After successfully guessing the other’s Secret Fractions, each one guesses the 3 respective Colors – of each Fraction Code.

**Step 5:** Once they have successfully guessed the other one’s Secret Fraction Codes, have them, TOGETHER then, add all 3 to make the Whole Number One 1.

Eg/ Susan’s Secret Fraction Codes look like this:

3/12 + 2/12 + 7/12 = 12/12 = 1

Bob’s Secret Fraction Codes look like this:

3/12 + 6/12 + 3/12 = 12/12 = 1

**Last Step:** Everyone share their Chocolate Bars with The Teacher! lolololololol

Enjoy! Yum.

**Love The Earth!**

Remember to Recycle both the paper and the tinfoil or plastic that the bar was wrapped in! The more Recycling and Care for The Earth, the more Pretty Colored Feathers (or Stars)you receive from The Teacher!

Yum! Your students are so lucky. Today I wrote about math on my blog for the first time ateachers.bagoftricks.com for a Hanukkah lesson and then was interested in how other people blog about math. This is great
