This activity allows students to expand their understanding of fractions and apply it to their daily life. Students will be given a story starter( I've included 2 for differentiation), which explain how Molly needs to double or quadruple her hot chocolate recipe. Students will write out the new recipe, which could act as a quick assessment tool. An answer sheet is included for a quick grade. :)
You could easily turn this into a narrative writing activity as well, where the students finish the prompt and add more details.
