# Royal Show Time

Published about 1 year ago by Ann Baker

Royal Shows are wonderful maths opportunities!

Breeders show off their farm animals, the best jam or the best cake is judged, not to mention the fashion parades, dancing dogs and the rides and of course the show bags.

So here is a show bag problem.

I last tried this problem out in Canberra and found that the numbers chosen made for some very revealing information about the Year 3-4 class that I was working with.

## Show Bags Problematised Situation

My friend, the Grade 1 teacher, is going to make show bags with her class. They are going to swap them with the class next door. The class has to make 26 show bags. This is what they have decided to put into each bag:

• 2 bouncey balls
• 5 balloons
• 3 dice
• 10 counters
• 4 sticks of chalk

My friend wants to know how many of each item she needs to buy ready for the show bags. I said you would work it out for her. She also wondered how many items they would be packing altogether.

And then, when the problem solving work is underway, a stretch for the more able in your group ...

A Sting in the Tail

• Bouncey balls come in packets of 10.
• Balloons come in packets of 10 as well.
• Dice come in packets of 6.
• Counters come in bags of 50.
• Chalk comes in boxes of 12 sticks. How many packets of each item will she need to buy?

While on the subject of show bags, a hot topic for some data collection...

## What should be in a Perfect Show Bag?

• What 6 things would you like to have in your perfect show bag?
• Are these the same or different to things that the rest of the class would like in their show bag?
• How could you decide what to put into a show bag for the boys/girls in your class?
• How could you decide what to put into a show bag that suited the whole class?
• What data/information will you need to collect to be sure that you have made the best decisions?

Think about how to present your information clearly to the class to see if they agree.

If you try this idea out, expect it to last for more than one lesson, but do send us your ideas with supporting data and we may put it on the blog for others to see. Who knows maybe a manufacturer would listen and next year you might have the perfect show bag.
