This activity follows on from World of Tan 6 - Junk.
It was almost a week after Mr Cheung moved into his new restaurant that everything went wrong. The gold plaque of the goose that had been passed down through generations of Mr Cheung's family could not be found anywhere. Obviously, those at Granma T's had lost it or stolen it.
Mr Cheung was both angry and disappointed. At first, Granma T was calm and composed. She tried to reassure Mr Cheung that the plaque would be found. If all else failed, she would pay for a replacement! It was then that Mr Cheung exploded, "The plaque is a priceless family heirloom, it cannot simply be replaced! Besides, the beak of the goose alone would cost one thousand Chinese yuan."
Granma T slumped into her chair. She was shaking and there was a tremor in her voice as she barked orders at everyone. The children were sent off to thoroughly search the packing cases. The workers were sent back to the old business premises. They were to search every corner of the building and back yard. No stone was to be left unturned!
"How could we have been so careless?" wondered Granma T.
In the meantime, complete the silhouette of the Golden Goose plaque as last seen.
Make a cube out of straws and have a go at this practical challenge.
