We all imagine of living in pristine surroundings so why don't we make a 3D replica of a nice cottage, which we can send as a card to our friends and family.
We just need carboard paper, normal paper to join the cardboard pieces, color pencils and lots of glue.
First cut 4 equilateral triangles (2 yellow and 2 white) on a cardboard paper and join them alternate color by sticking small strips of paper underneath to make a square pyramid. If you press this pyramid you will get a rhombus. Press it so that the pyramid always folds this way. Cut 2 rectangles of slightly bigger width and length than the folded rhombus. Stick these rectangles on the white triangles. Now when you press you should be able to fold it completely and will see this structure. This is the roof of the house.
Make another large rectangle which will make four walls of the cottage. The length of rectangle should be 4 times the side of the triangle. Make doors and windows on each side. Now place the roof on top of these walls and stick two adjacent bases of the triangles of the roof on the walls. And now when press the walls the whole house will fold with roof moving up.
Just like we did to the base of the triangles, stick same two adjacent base of the walls to the ground cardboard on which the house will stand. This ground can be a larger cardboard cover of a book. And the cottage is ready to move in. You can also have another background of the house will hills as backdrop.

Hope you enjoyed making the 3D house. ANd now its time to think.
When you were making the roof you made a square pyramid with 4 equilateral triangles. Try making a triangular pyramid with three triangles. And measure the volume of the two pyramids. How much less is the triangular pyramid.
Can you make a pentagonal and hexagonal pyramid with 5 and 6 equilateral triangles respectively.
