We had just two submissions for this challenge, with pictures showing what they found.
Yihang fromWembdomSt George sent in this picture:
Lily from St. Kevin's Geebung in Australia sent in four pictures, the first shows her answers and the next three shows where she went with successfully exploring other shapes.
Larger versions of those three are worth a look here.
Well done the two of you, maybe others will feel they want to explore further.
Andrew decorated 20 biscuits to take to a party. He lined them up and put icing on every second biscuit and different decorations on other biscuits. How many biscuits weren't decorated?
