We had to use the Base 10 equipment to create some models…but there was a twist:

#### Can you make a model of a robot in Base 10, that is symmetrical?

What is the total value of your model? Does the fact that it is symmetrical influence its value?

## Can you design an animal that has an odd value?

What will determine if the number is odd or even? Which is the most crucial type of Base 10 block in the model? Why?

### Can you create a house, using Base 10, that has a total value as close to 500 as possible?

What happens when Mr. Swallow comes along and pinches some of your equipment? Is it more important to get to 500 or to make it look like a house?
