World of Tan 1 - Granma T

Age 7 to 11
Challenge Level

Hello, I am Granma T.

I am an elderly business woman living in the Guangdong province of southern China.

My business is Removals! Naturally, I can't do this all on my own.

I have help from my two grandchildren, three workers and a personal assistant. You will meet all of these people when you join us on several adventures in the months to come.

There are seven of us, just as there are seven pieces in the ancient Chinese puzzle, shown here:

Tangram

Can you complete my silhouette using the seven pieces from the tangram with the interactivity below?

Can you complete the logo of my removal firm?

Extra activities:

Can you find out Granma T's age? It is one more than a square number and it has four factors. The sum of the digits of her age is 11.
