The purpose of this Warm-up is to elicit ideas about baking, which will be useful when students solve a problem about a recipe in a later activity. While students may notice and wonder many things about the image, baked goods with which students are familiar and details about the process of how those baked goods are made are the important discussion points.
What do you notice? What do you wonder?
Recipe and Fractions Handout
The purpose of this activity is for students to familiarize themselves with the structure of a recipe and consider the mathematical questions that could be asked about a recipe. When students wonder about what mathematics is involved in a situation, they model with mathematics (MP4). A blackline master of a recipe has been provided. If available, have students use cookbooks or internet enabled devices to look for recipes that interest them.
The purpose of this activity is for students to use what they have learned about multiplying and dividing fractions to solve a problem involving a recipe. Students have to figure out a way to measure the ingredients for a recipe using a limited set of measuring tools. They have to look for relationships between the amounts that need to be measured and the tools that are available. When students model a situation using a representation such as a drawing or equation, they model with mathematics (MP4).
Noah wants to make banana bread using this recipe. He only has a cup measuring cup and tsp. How can Noah make this recipe using these 2 measuring tools? Show your thinking using drawings or equations.
“Today we used what we’ve learned about multiplying fractions and dividing whole numbers and unit fractions to solve a problem about a recipe.”
“How were some of the relationships between the measuring tools and the amounts in the recipe helpful as you solved the problem today?” (I knew that I could make 2 out of groups of , which helped me think to divide 2 by to find how many quarter cups he needed to measure the flour. I knew that I could multiply by a whole number to get which helped me figure out how Noah could measure the brown sugar.)
Consider having students respond to the previous question as a journal prompt.
