When you measure out ingredients you use math skills. Basic measuring skills can be taught just by using the dough recipe . Higher level math skills can be used when figuring out the cost of each pizza. Real life problems and incidental learning are a great way to acquire and reinforce various skills. Observing how the yeast is activated with warm water and sugar, is a science experiment.
Yeast is actually a living organism.
Rising dough is not a chemical reaction, but actually a biological process. OK, I am sounding a little to scientific here, but you get the idea. Describing the taste and smells of the pizza can allow you to increase vocabulary and writing skills. Brain-storm and write down a list of descriptors. Then, use a dictionary or thesaurus to help you add words to the list.
