One of the most common math problems I run into on a regular basis is how to modify a recipe according to the number of ingredients in my pantry. I often decide to bake on a whim and don’t always have enough ingredients to complete the entire recipe. Today I was starting a batch of my kids favorite blueberry muffins, but when I went to put in the eggs, I realized I only had 3 eggs and the recipe called for 4. I could have went to the store, but it was 5 degrees outside and I wasn’t up for the trip. So instead, I decided to modify the recipe to fit the parameters of 3 eggs.
Missouri Learning Standard(s) 5.NF.B.6, 5.NF.A.1.
What do you notice? What do you wonder?
How much of each ingredient will I need to make the recipe using 3 eggs?
You can provide the recipe ingredients in Act 2 to have students do some estimation about what fraction of the ingredients will be needed?
What information do you need to help you solve the problem?
If scaffolding is needed you can use these pictures to help visualize fractions.
Some of my pics didn’t turn out, so for now I just have amounts next to the pics of the ingredient. I will fix this when I get a chance to take pics of the measurements:)
