This morning is a great example of this. We had muffins for breakfast. I prefer making them from scratch but when the kids are making them we use packaged mix so that J can do all the work himself. The mix we buy only requires 1/2 cup of milk to be added. The kitchen is my favorite place to teach fractions! He measures it out and stirs it up, while I preheat the oven and spray the pan with bakers spray.
Next he uses the cookie dough scoop to fill the muffin cups. This is great for measuring practice, as well as discussing volumes. The whole time he is learning to control his body and developing hand eye coordination!
