COOKING CUPCAKES

TASK

Our task was to make either cupcakes, jelly, pizza or pikelets. I was the group leader and my group made cupcakes. There were six people in my group. Me, Ryan, Leila, Flynn, Martin and Ella-Lucia. After we made our food we had to work out how to adjust the amounts of ingredients to serve 100 people (1 each.) This is how we worked it out…

THE INGREDIENTS

• 1 cup of butter

• 1 cup of sugar

• 1 ½ cups of self-raising flower

• 1 egg

• ¼ of a cup of milk

(This only makes 20 cupcakes.)

DOUBLING THE INGREDIENTS

Before we worked out how to adjust the amounts of ingredients we needed to double it.

• 1 cup of butter x 2 = 2 cups of butter

• 1 cup of sugar x 2 = 2 cups of sugar

• 1 ½ cups of self-raising flower x 2 = 3 cups of self-raising flower

• 1 egg x 2 = 2 eggs

• ¼ a cup of milk x 2 = ½ a cup of milk

(This now makes 40 cupcakes.)

WORKING OUT THE MULTIPLES

The next thing we did was working out how many times the amounts of ingredients go into 100. First we broke the problem down and said if 2 goes into 10 5 times then 20 will go into 100 5 times! We just added a zero! So 20 x 5 = 100.

MULTIPLYING THE INGREDIENTS

So if the answer is 5 (we worked it out in the previous slide) all we need to do now is to multiply the amounts of ingredients by 5. This looks like:

• 1 cup of butter x 5 = 5 cups of butter

• 1 cup of sugar x 5 = 5 cups of sugar

• 1 ½ cups of self-raising flower x 5 = 7 ½ cups of self-raising flower

• 1 egg x 5 = 5 eggs

• ¼ of a cup of milk x 5 = 1 ¼ cups of milk

(Now this makes 100!)

WHAT I HAVE LEARNT

I have learnt how to multiply fractions (my group taught me) e.g. ¼ a cup of milk x 5 = 1 ¼ cups of milk. I have also learnt how to make cupcakes!
