Work on your own or in small groups to do the following.
1. Take the two pieces of construction paper and lay them on top of each other as shown.
2. Fold the pieces of paper so that the flaps are roughly the same size and staple the top to secure it. Your booklet should have 4 flaps.
3. Look up the recipe for your favourite brownies, cookies, or cake. The only requirement for the recipe is that the list of ingredients must have at least 4 fractions in it.
4. On the first flap of the booklet you created label it original recipe and indicate the amount of servings it will create. Then write down the ingredients necessary.
5. On the second flap mark it as \frac{5}{6} of the original recipe. Next to this, indicate the servings this new recipe will produce. Above this label write the amount of each ingredient that will be required to make \frac{5}{6} of the original recipe.
6. On the third flap mark it as \frac{4}{5} times the original recipe. Next to this, indicate the servings this new recipe will produce. Above this label write the amount of each ingredient that will be required to make \frac{4}{5} times the original recipe.
7. On the fourth flap mark it as 15 times the original recipe. Next to this, indicate the servings this new recipe will produce. Above this label write the amount of each ingredient that will be required to make 15 times the original recipe.
8. Add any design the booklet that you would like using your crayons or markers.
Work with a friend for the following questions:
Test it out! Pick one of the flaps in the booklet you’ve just created and try baking your chosen recipe according to the amount of each ingredient you calculated. Did it produce as many servings as you predicted?
