Objective Statement Our Objective Statement: The students will measureunits of ingredients of browniesby using fractions.
Video Objectives Part One: Introduction of Lesson. Establish and Engage. Part Two: Activity, Speech, or Lesson. Explore, Explain, and Extend. Use a variety of teaching methods: Visuals, music/songs, games, hand-on, group-work, etc. *Use HOTS (Higher Order Thinking Skills). Part Three: Review Lesson. Evaluate.
Rationale
Written rationale clearly describes how the video hook and questions will help students connect to the content through real world applications, humor, and/or mystery.
One or more paragraphs with specific examples and details from the video and questions.
This video hook will attract the student’s attention in a fun and interesting way, but also in a practical and worldly sense by introducing whole numbers and fractions in regards to measuring ingredients for a brownie recipe. In the video Erin will be inspired by Jocelyn’s cooking show to prepare brownies for her friends. When she realizes Jocelyn’s recipe only serves 12 people she must find out how to double the recipe for her 24 friends. Narrator Dorothy helps answer Erin’s questions on how to add fractions to double the recipe. Through visual graphs and entertainment, students will learn both what a whole number and a fraction is, and how to use that knowledge for everyday use.
Incorporating NC Standards Teaching and Learning Standards:
Provide the specific standards to which your video hook applies, listing them from the state or national standards website. Then, write a brief statement that describes how you meet the standards in your video and questions activity, employing quotes from the standards and clear examples of how the media and technology are actively used in teaching and learning.
NC.K.MD. 1 Describe measurable attributes of objects; and describe several different measurable attributes of a single object.
NC.K.MD. 2 Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. Classify objects and count the number of objects in each category.
NC.K.MD. 3 Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
NC Standards Statement: The North Carolina Essential Standards are met by measuring the units of several ingredients for a recipe. Whole numbers and fractions are compared in measure by also comparing eggs as whole and milk, oil, and water as ingredients with fractions. The two categories used in the video are whole numbers and fractions.
Question Sets Question Sets with Model Student Answers (how teachers will guide/engage students)
Includes three or more thoughtful, open-ended, higher order thinking question sets that guide students’ learning experience.
Each question set includes detailed model student answers.
Each question set is connected to a specific time in the video where a teacher might pause to ask questions.
Question Set 1 (video at 1:17)
What kind of numbers are used to measure these ingredients?
Fractions. Fractions are a numerical quantity that is not a whole number. Each part of the whole is measured in equal amounts.
What is an example of a Fraction in our recipe?
An example of a fraction would be the ¼ cup of water or the ⅔ cup of vegetable oil. We do not need one whole cup, but a part of the cup.
What is an example of a Whole Number from our recipe?
An example of a whole number would be the eggs. The recipe requires 2 whole eggs, not just part of an egg.
Question Set 2
How many batches or servings does Erin want to make? (video at 1:41)
2 batches, or 24 servings for her friends.
How would you double a recipe? (video at 1:47)
By adding two of each ingredient together. ¼ + ¼ is equal to ½. All you have to do is add the numerator, or top number, because the denominators, or bottom numbers, are the same. 1+1=2. So put that 2 over the 4 and then simplify.
What would we do if we needed to triple the recipe for 36 servings?
By adding three of each ingredient together. ¼ + ¼ + ¼ is equal to ¾. We’d need ¾ cups of water. For the oil we’d add ⅔ + ⅔ + ⅔ to equal 6/3. The top number is larger, so we’d end up with a whole number! 6 divided by 3 is 2. We would need 2 cups of oil to triple the recipe. For the eggs we would need 2 eggs three times, which would be 6 whole eggs. And, of course, we would need 3 boxes of mix.
Question Set 3 Suggested Activity for your Class after the video
In your group, divide your play-doh into 3 or more pieces, separating three pieces from the rest. How would you write this in fraction form? Would you need to simplify? If so, why?
For example, if you divide your play-doh into 9 pieces, and you take away 3, your fraction would be written as 3/9. We can simplify this into ⅓ by dividing it by 3/3.
How many pieces do you have left after you subtract 3? How do you show this as a fraction? Can you simplify this fraction?
Following our previous example, we would have 6 pieces left of the original 9. This is 6/9. Simplified it would be 2/3.
Add your two fractions together. What did you get in fraction form? What does this represent?
Following our previous example, we will add ⅔ and ⅓ together to get 3/3. If done correctly this simplifies to 1. This represents a whole number.
Script Dorothy: Hey guys! Today we are going to be learning about fractions. I know…. It sounds scary, but Jocelyn and Erin are going to teach us how fractions can be oh so yummy...
Erin: (Erin Sits on her couch and turns on the TV) I am soooo hungry. Lets see whats on Food Network.
Jocelyn: (Hosting her tv show. Teaching viewers how to make Brownies) (Alarm rings, wakes up) It's Midnight! Welcome to Jocelyn's Midnight Snack! As always, I am so happy to see y'all, and I am hungry! So, before we head out to the kitchen, let me tell you what we're making tonight: Brownies! For this recipe, which serves 12 servings, we will need the following ingredients:
1/4 Cup of Water
2/3 Cup Vegetable Oil
2 Eggs
my famous pack of brownie mix
If done right, we will have some super delicious midnight brownies! Now let’s get started!
Erin: WOW, I want to make Jocelyn's famous brownies! (goes to kitchen and gets out brownie mix and other ingredients.) So she said all I need is a package of Jocelyn's Famous brownie mix, ¼ cup of water, ⅔ cup of Vegetable oil, and 2 eggs. Sounds easy enough!
Now that I think about it, those are some odd looking numbers.. [1st question]: I wonder what they are called? (Flash to whiteboard, Dorothy will narrate)
Dorothy: They are called Fractions. Fractions are a numerical quantity that is not a whole number. For example, if I have a pie cut into 4 pieces, and I only want one slice, this slice represents a ¼ fraction of the pie.
(Flash Back to Erin)
Erin: Ohhh now I get it. I need to make enough for 24 people. Maybe I should double the recipe. [2nd question] What is ¼+¼ ?
(Flash to whiteboard, Dorothy will narrate)
Dorothy: ¼ + ¼ is equal to ½. All you have to do is add the numerator because the denominators are the same. 1+1=2. So put that 2 over the 4 and then simplify.
Erin: So, I really need a half cup of water, 4/6 cup of vegetable oil and 4 eggs. (Erin measures out ingredients and begins to make brownies) (buzzer goes off and erin pulls out brownies) Mhhhhh these look soooooo good. I cannot wait to share them with my friends.
Dorothy: So today we learned that if feeding a large group you can double the recipe by adding the fractions of the ingredients. See fractions are not so scary. They can be quite delicious!
