Cupcake Fractions

Cupcake Fractions and Ratios

By Alessia and Georgia

Last Friday Miss Lee organised us some fun food activities. She bought cupcake mixes (chocolate and vanilla flavour) and green cordial. There were also other activities like the fraction flag activity. We were split into groups for the day when we did this.   

We made cupcakes using ratios and fractions.   

 

 

We had to mix some vanilla and chocolate then write the ratio and fraction for it. For example 3 spoons of chocolate and 1 spoon of vanilla. The ratio would be written like this 3:1 and the fractions ¾.  

We then did the same with the cordial 20 mL of cordial and 40 mL of water had 1 part cordial and 4 parts water.  It had a fraction of ⅕.

Chocolate Fractions

By Abby and Matt D

Our Year 5 class have been learning about fractions. Last Thursday we played the chocolate fractions game.  In the chocolate fractions game we had three chairs at  the front of our classroom with chocolate packs on them.  The first chair had one pack of chocolate. The second one had two chocolate packs on it and the third had three packs of chocolate. Year 5 had to pick which chair would give them the most amount of chocolate.

Kameron had the first choice and that was easy (he chose the seat with 3 packs).  From then on more students had the chance to come up to the front of the classroom to pick what chair they would get the most chocolate from.

We had whiteboards to see what fraction it would be, sometimes all the groups would have the same fraction which is called an equivalent fraction e.g 1/3,  2/6, 3/9. We would have to think and use our fraction brains to figure out the option would be the best and give us the most chocolate.

Which option you would choose?

Option 1- You would have 1/5 of the chocolate (1 bar)

Option 2- You would have 2/9 of the chocolate (1 1/9 bar)

Option 3- You would have 1/12 of the chocolate (1 3/12 bar)

What did you learn from the chocolate fractions lesson?
