WHO ARE YOU?
In the Chapter 8 Chapter Task you designed a petting zoo. Sometimes the
animals may be hiding or sleeping, so it helps if there is a sign that
tells people which animal they are looking for.
Your teacher thinks that is a good idea that the class makes signs for
the animal pens. The sign will include the name and a tangram of the animal.
Practice making animal tangrams on the Internet, then download tangram
puzzle shapes. Describe each of the shapes and estimate, then measure
their perimeter and area.
Make 2 signs using tangrams of 2 of the following
- a pony
- a dog
- a chicken
- a rabbit
- a duck
- a cat
