One thing that is pretty certain, is that your kids will need to use math in the kitchen consistently within their life. Another certain thing is that kids like cake. Agreed? What if your kids got to complete their math lesson in the kitchen today? I guarantee there will be cheers and fist pumps and long, drawn-out "YESSSSSSSSSSSSSSES".
This fun math lesson and FREE PDF combines the skill of doubling a recipe and making sure there is enough food to go around to all guests, and how to troubleshoot when the number of guests change. It will also take students through the process of finding the area and perimeter of a 13" X 9" cake.
I recommend making the cake first before allowing your kids to complete this fun assignment. It will be more relevant for them, and what kid doesn't love the promise of something yummy to eat at the end?
I found the original recipe here, and you will find my altered recipe below. Among other changes, I subbed the shortening for coconut oil and doubled the recipe to make enough for a 9"X13" cake. (Pour the batter to fill the pan about 3/4 full. There may be extra batter. I use it to make a couple of cupcakes....for testing of course! ;)
Let me tell you, this cake will become a staple in your home! It is so amazing!
Here is the recipe that needs doubling (included in the FREE PDF):
When the cake is removed from the oven and has cooled, allow your kids to measure the cake and find the area and perimeter. The cake is included in the PDF, ready to measure, but it's even more meaningful to use the actual cake and not just a picture.
In the worksheet, your child will have the opportunity to create an array with the cake, using the picture below and based on the amount of people eating dessert.
They will also get the opportunity to tell how many people the cake below will feed. Take this time to explain how to figure out how to cut the cake based on the amount of people coming to dinner.
What happens if each person asks for two pieces? Or what would you do if twice as many people showed up? These problem solving questions have more than one right answer, and will get kids thinking about everyday math and will give them the opportunity to explain their thought process. What a deliciously relevant way to talk about math!
