We were looking at the logo for the Commonwealth Games and a great question came up.
What do those X's mean?
So we learnt about Roman numerals.
I=1 V=5 X=10 L=50 C=100 D=500 M=1,000
There were some rules we had to follow
*When a symbol appears after a larger symbol it is added.
*When a symbol appears before a larger symbol it is subtracted.
*You are not allowed to use the same symbol more than 3 times in a row.
With buddies we worked out how to write numbers in roman numerals and challenged each other to write tricky numbers.

We finished off by working together to make the number 8 with our bodies. We had to work out how many people we needed and how to create the number 8.

| 5+3=8 |
And we worked out it is the 20th Commomwealth Games.
Thank you Mrs McFadyen for the inspiration for our maths learning. We had lots of fun and learnt heaps.
