If your cake is not cooking in the middle, then pop it back into the oven and cover tightly in tin foil. The tin foil will trap the heat and help to cook the inside of your cake. Bake for another 10-15 mins checking after 5-7 mins to make sure it's working.
It's happened to me. I learned to use a toothpick, knife or cake tester (thank you pampered chef) to monitor if the cake is done. It's really an easy way to formatively assess whether the cake is ready to leave the oven and become 'proficient'.
We often are puzzled why students aren't able to successfully navigate grade level math problems. Math is an abstract concept. When you are learning a topic, pure abstraction can be a good way to get lost. It helps to find a specific, concrete meaning for the abstract ideas. I challenge you to move students through these stages and when they get stuck or seem to not understand look toward concrete to insure understanding.
- Concrete “doing” stage: Make sure you spend time here with student evidence of solid understanding. When you have a few students who may not 'get' the math. Differentiate and give them manipulatives to use while other students move on to the next stage.
- Representational “seeing” stage: The resource takes lessons here quite quickly. When you find that you are explaining more bring in manipulatives as a scaffold to support transition.
- Abstract “symbolic” stage: Clearly this is the quickest and most efficient phase. However, kids can not move to automaticity without concrete and representational understanding. Simply memorizing will limit how they use strategies.
The cake needs more time.
