On Tuesday, we built a chair called 'sandwich', because the chair is like a sandwich.

First ,we have think a lot of ideas, like square shape so on.

Then, we chose a triangle shape idea to make the chair.

Our material include 6 triangle-shaped blue colour stryofoam, 18 cardboards. Then we cut all out  and stick it.

Now our groupmate testing the chair!

Finally, we present it. And the chair can sit two children or an adult.
