Standards

CCSS.MATH.CONTENT.5.NF.B.7.A Interpret division of a unit fraction by a non-zero whole number, and compute such quotients.

CCSS.MATH.CONTENT.5.NF.B.7.B Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient.

CCSS.MATH.CONTENT.5.NF.B.7.C Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem.

Background Knowledge

Prior to this lesson, students should understand unit fractions and basic concepts in dividing fractions. This lesson gives students the opportunity to practice creating and solving problems where they have to divide fractions or divide by fractions, which can be easily differentiated based on student skill level. 

Instruction

1. Introduce students to Bake-a-Palooza and have them play the game. The first time they play it, have them answer questions correctly. The second time they play it, have them answer questions incorrectly and watch the instructional video that plays.
   • NOTE: The Bake-a-Palooza game is also available in Spanish. Hornea Hasta Que Lo Logres
2. Explain that to practice dividing fractions, they are going to be creating matching questions for a new version of Bake-a-Palooza. Show the questions currently in the game as an example. 
3. For each matching questions they add to Bake-a-Palooza they should have:
   1. Fractions that are divided by whole numbers or whole numbers divided by fractions. 
   2. Visual models for each equation
4. Have students create a real world problem using their fractions and visual models that could be used to create a “chapter 2” of Bake-a-Palooza. 
5. Have students share their game ideas with others for feedback. Students can solve each other’s problems to double check their work.

Extension

• Students can create videos to teach students who incorrectly answer questions in the game.  If having students use their own phones to create videos, we suggest doing this activity at the end of class to minimize the number of times you need to say, “Please put your phones away.” Also, plan to have a few iPads or Android tablets available for use by students who don’t have a phone. If video editing software is available for computers or tablets, this lesson can be followed up with use of those computer applications.
• Students can create multiple chapters of Bake-a-Palooza based on the three different parts of the 5th grade standard on dividing fractions.
