<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 14pt; font-style: normal; text-decoration: none; vertical-align: baseline;">**Part I: Learning Activity**
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">1. Have the students work in pairs for this activity. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 2. Read the following to your students: "In a Cyberchase For Real episode, Bianca is helping a friend bake cupcakes for a party. Bianca's friend is supposed to bake 24 cupcakes, but her recipe only has the ingredients listed for 12, so they have to double the recipe. When you have to adjust the amounts of a recipe, there may be several strategies you can use. In this activity, you will try out ways of adjusting amounts in these recipes and develop your strategies." <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 3. Distribute Handout 1: Grandma’s Gittel’s Favorite Cupcake Recipe. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 4. Ask the students to complete the ingredients list for 24 cupcakes, and fill in the table in Handout 1. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 5. Tell the students that they will watch a video clip in which Bianca and her friend try to figure out the amount of ingredients to use to make 24 cupcakes. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 6. Play the Right Amount of Cupcake Mix video Video and ask students to write down Bianca's ingredient list as they watch. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 7. Ask the students to compare their results in Handout 1 to Bianca's ingredient list in the video clip. Did they notice that they had to double the ingredients before viewing the clip? <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 8. Tell the students that now that they have doubled the ingredients in the recipe, they will try out three different strategies for doubling. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 9. Distribute <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;"><span class="wiki_link_ext">Handout 2: Three Ways to Double Fractions <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 10. Ask the students to complete Handout 2. Encourage them to compare the three methods for doubling as they complete the handout. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 11. Tell the students that as they examine recipes, they will find that some ingredients are listed in fractional form. Some of these will be improper fractions, and some may be mixed fractions. Because all these forms are common, they need to learn how to convert them.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 12. Distribute <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;"><span class="wiki_link_ext">Handout 3: Converting Mixed Numbers and Improper Fractions <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 13. Ask the students to read and discuss Handout 3. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 14. Discuss converting mixed numbers and improper fractions with the students. Make certain that the students understand the distinctions between mixed numbers and improper fractions. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 15. Tell the students that doubling mixed numbers is probably easiest if they convert the mixed number to an improper fraction, and then double the improper fraction. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 16.

Ask the students to read Handout 4, and complete the problems. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 18. Discuss with the students any problems they had in doubling the mixed numbers, or converting mixed numbers to improper fractions, and vice versa. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 19. Introduction of the problem will be introduced at the end of this lesson.
